How Common Is A False Positive Pregnancy Test And What Causes It?



False Positive Pregnancy Tests

Home Pregnancy Tests

The best way to get accurate results when using a home pregnancy test is to wait until your period late. At that time, the level of hCG in your sytem will be large enough that all of the pregnancy tests on the market will be able to detect it, producing a positive pregnancy test result.

Most women, who are trying to get pregnant, prefer to find out as soon as possible. That “two week wait” becomes unbearable. There are many home pregnancy tests on the market that claim you can test much earlier, usually 4 or 5 days before your period is due. These early test pregnancy tests are typically about 97% accurate, when all the instructions are follow exactly and you read the results within the time frame listed in the instructions.

What Can Cause False Positive Pregnancy Test Results?

A truly “false positive” test result, due to a faulty home pregnancy test is fairly rare. A positive result which is not repeatable, with subsequent home pregnancy tests, is usually because of one of these reasons: Chemical pregnancy, missed reaction time, chemical interference or an evaporation line on the pregnancy test.

Chemical Pregnancy

As unfortunate as it is, about 25% of all pregnancies end up being a chemical pregnancy, also known as an early miscarriage. A chemical pregnancy happens when a pregnancy is lost shortly after implantation. With the advancement in sensitivity of the home pregnancy tests on the market today, women are able to detect pregnancy in the very, very early stages. This is the downside of the super sensitive pregnancy tests – the joy of discovering pregnancy very early on, followed by crushing heartbreak if an early miscarrige occurs.





Missed Reaction Time

You really need to follow the instructions included with your home pregnancy test exactly. The manufacturer lets you know how long you should allow the test to sit before interpreting the results. If you let the test sit for longer than the instructions state, any results you interpret need to be considered invalid. Reading after the recommended time frame has passed can show results that you will misinterpret as a positive result.

Chemical Interference

If you are undergoing fertility treatments and have had a hCG (Human Chorionic Gonadotropin) trigger shot, you will need to make sure the shot has had enough time to metabolize through and clear your system. Fertility doctors suggest waiting about 14 days for your system to be clear of the hCG before taking a pregnancy test. Testing before this time may very well likely produce a positive result when you are not truly pregnant.

Evaporation Lines

Some pregnancy tests can leave an evaporation line on the pregnancy test, as the urine crosses the result area. The evaporation line is usually a very faint, grayish line in the results area of the pregnancy test. The color of the line is not what the test instructions say should be there, for a positive result, but many women, will erroneously interpret the line as a positive result.

If you feel you are having early pregnancy symptoms and not getting the results you think you should be from your home pregnancy tests, you should contact your doctor for a blood pregnancy test.

    i took two clear blue digital tests 20 min apart. the first one was positive the second one was negative. is it possible its a false positive?

  • http://www.earthsmagic.com/ Vickie B.

    It isn’t something that happens often. Maybe your level of hcg is low right now. If you used two different batches of urine to test, the first one could have been more concentrated as it had longer to build up in your system. If you urinated again 20 minutes later to test, it could be the hcg just didn’t have enough time to build up again. This would be especially true if you haven’t missed your period yet.

  • terri

    My husband and I have been together for 8 years and have been trying to conceive… I have thyroid disease and my cycle has never been accurate. I’m 90 days in which has happened before but this prompted me to take a pregnancy test (clear blue digital) yesterday morning at 4 am and it was positive and then I took another at 3 pm and positive… Now I worry that they are both wrong just cause of all the issues I have had in the past.. What is your opinions? I am making a dr apt tomorrow to either confirm or crush this feeling… Confused and Nervous

  • http://www.earthsmagic.com/ Vickie B.

    Hi Terri! Sorry it took so long to reply. :( Did you get confirmation from the doctor?

  • Jessica

    I took 5 hpt total. First was 3 days before missed period with clear blue digital at 4:30 am, said pregnant. Tested again later that same day results, not pregnant. Decided to wait until the day of my period took 2 more tests this time a store brand both negative results. Now I am 4 days late and toik another clear blue digital hpt says not pregnant. Should I trust the very first test that showed pregnant? Confused…

  • http://www.earthsmagic.com/ Vickie B.

    If you tested with first morning urine on the second clear blue, then unfortunately, it sounds like you may have had an early miscarriage. If you didn’t take it with the first morning urine, try again, limiting fluid intake and holding your urine for as long as possible.

  • Jessica

    The second clear blue was not first morning urine. The first store brand was but I didn’t pee for 5 seconds on the stick. I’m now 5 days late for my period. Still no cramping or any signs of it coming.

  • http://www.earthsmagic.com/ Vickie B.

    I would suggest that you try again with another test but make it the FMU. If you are pregnant, that should show up positive.

  • Sara

    Hi, I was sterilised 5 years ago and i’m 4 days late (im never late), so I took a test (not morning) said “preganant, i waited til I needed to pee again and took the 2nd to make sure and it came back ” not pregnant”. So I’ve done another this morning (FMU) and said “not pregnant” again…. sooo confused!!

  • http://www.earthsmagic.com/ Vickie B.

    False positives are pretty uncommon with the popular pregnancy test brands. The fact that you were sterilized makes a positive even more odd. If your period doesn’t arrive soon, I’d suggest a visit to the doctor and explain what occurred. Sorry I couldn’t shed any sort of light on this issue for you.

  • sara

    Yeah, i have spoken to an out of hours doctor, I’am going for blood tests tomorrow morning (monday) to try and get some answers. I still have no sign of a period but I’am cramping and feeling sick now, so don’t know whether thats a good sign or not

  • http://www.earthsmagic.com/ Vickie B.

    Good luck! Hope you get some answers that feel good to you!

  • Jmcat01

    Ok so I took a clear blue pregnancy test last night and it said I was pregnant then I took on this morning and it said not pregnant…idk what go think

  • http://www.babyhopes.com/ Vickie B.

    It could be that you are testing a tad too early. Wait a day and try again. Try and make sure you are not drinking much liquid for several hours before testing so the hcg has time to build up in your urine.

  • Gabby

    I am 10 days late on my period and took a test which to my surprise came back positive, this is because I have PCOS and believed it would be hard to get pregnant. However, after having a positive I took another one to show my partner which came back negative. All together I have taken 6 pregnancy tests and had 5 negative and 1 positive. Why is this, I’m confused and don’t know what to do.

  • Mil

    I did a hpt this morning it was a faint positive I went to the doctors they’re test was negative Iv has a blood test but got to wait for results. I done anothe test when I got back another faint positive help??!!

  • http://www.babyhopes.com/ Vickie B.

    It could be that you have very low levels of hcg. By now, the positive should be much darker if you are pregnant. It could also be that you had a very early miscarriage. If that is the case the pregnancy tests would be showing a negative by now.

  • Sarah

    Hi, I went to my Ob-Gyn last week and she made an ultrasound for me. She said that I am pregnant but no fetus/embryo was present. There’s no yolk sac, either. But it said that it’s 6 weeks already, and as I am typing this it’s already 7 weeks. I don’t feel any symptoms that I am pregnant, except for my head aches sometimes and feel tired easily. Is it false pregnancy? Thanks

  • http://www.babyhopes.com/ Vickie B.

    You will need to contact your doctor about this to find out exactly what she means and what it means for you. If there isn’t an embryo present, I would think that it isn’t a pregnancy, unless what actually an early miscarriage that hasn’t completed yet.

  • Krista

    I am 42 yrs old and I just finished chemotherapy for NHL in Feb. , which forced me into menopause. The oncologist told me that I would resume my normal cycle about 2 months after completion of chemo. I got 2 sort-of periods that stopped about 2 months ago . I started getting the hot flashes with no period after that and went for my yearly at the gyn. I was just informed that I MIGHT be pregnant! They said they tested my urine and there was a line in the positive, but was faint…I have to wait now for blood results. What are the chances?!! What does a faint line mean??

  • Ashley

    So I had my period on July 5th and August 6th. It lasted till the 10-11th. I had unprotected sex and my bf didnt pull out on the 14th. Usually I know when my period is coming bc I get massive cramps and I get emotional & grumpy. It’s now the 11th & no signs of my period. Which I expected to arrive around the same time. I took an expired test and said neg so then I bought a new one and took it at night and said neg. yesterday the 10th I drank water all day and up till midnight bc it’s all I rly drink. Today the 11th at 5:30 I took another and said neg. is it possible the water is diluting the test for a false neg? I don’t understand how neg tests but no period. I haven’t changed anything to delay my period. And I find it crazy that it would be “delayed” the month after unprotected sex. I’m not sure if I should wait and take another test, wait for my period, or schedule a doc appt for a blood test. HELP! I’m just not sure if I would be considered far enough based on when I had sex to determine the test positive. Feedback plz. ( & no rude comments, yes I am old enough for a child. & two I do want to be pregnant. Just not sure why neither are appearing )

  • Emily32013

    I had my tubes tied in October of 2012 and I recently missed a period which could easily be due to stress but I took a test Bc I have been nauseous, dizzy And just didn’t feel right. It was negative at first then it showed a faded line positive after the time . Ok so I repeated the test the next day and the same thing happened. I did have a two day period though. Could I be pregnant? There’s no way right??

  • Adebisi Ayannusi

    It is becoming a common occurrence
    when you do a blood pregnancy test and giving a positive result but the truth is that the patient is not pregnant. Pelvic Scan was carried and showed no evidence of cyesis. It comes worrisome as one of the patient is still intact. Much as i know that a choro – carcinoma can result in false positive, does it mean that these young women are in that group?

  • Amanda

    I’m 4 days late so I took 3 home test and they were all positive. I go to the doctor and it was negative! I don’t know what to think.

  • Kelly

    I am a week late. I took a clear blue easy test. The line is faint. But it’s positive.. Then I took the dollar store pregnancy test. The line is still faint, but it says positive! Am I really pregnant?! :)

  • bianca

    Hey so if you take a pregnancy test right and the first one you take it says negative then the next one to take it says pregnant and then you take another one and it says negative that means your still pregnant right cause the one that said pregnant

    My wife and I have been trying for 16 months with a fertility doctor using the creighton model. On 5-20 we saw him and he told her to use fermara once on that same day and keep charting. Once peak day passed start using progesterone. Well it has been about a week without and peak type mucus and she took a test yesterday which came back pos. Is there any way fermara caused a false positive? We have a blood test today to confirm or deny. I have yet toset my hopes up high to see them cut back down, she is pretty excited of course. Hopefully its not a false pos and I can be as excited as her and not have her feel bad for my lack of excitement at this time.

  • Preston Carpenter

    My wife has been feeling real tired lately. She bought to pregnancy test. The first was positive, the second was negative. She then went to Walmart and bought four more test. They all came back positive. She has been eating a lot and sleeping all day. Three weeks later she had a period for about three days. She then went back to Walmart and bought another and it came back negative. Why is this?

  • Danielle G

    What happened? Were you pregnant? That’s happening to me right now. I don’t know what to do…

  • http://www.babyhopes.com/ Vickie B.

    The first set of pregnancy tests could have been taken early on in the pregnancy where extra liquid intake could have diluted the hcg concentration so it showed up as a negative pregnancy test. The three day period could have been a miscarriage. You should have discussed this with a doctor.

  • Victoria white

    I took a pregnancy test yesterday and it came out negative. ..then i took one this morning it came out positive. ..then later today i took another one and its negative again. ..what does this mean?

  • http://www.babyhopes.com/ Vickie B.

    It could just mean that you are in the very early stages of pregnancy where your hcg levels are very low. If you drink excess liquid before testing it can dilute the hcg level to a point where the test can’t pick it up.

  • Victoria white

    The positive sign was kinda blurry when i took it but minutes later it was clear as day …i haven’t had my period since may 11 and still haven’t got it yet im confused because i have an irregular period. And i dont know what to think

  • http://www.babyhopes.com/ Vickie B.

    Take another test tomorrow first thing when you get up. If you are pregnant, you should get a positive more quickly than this time. You can also go and see your doctor to see if they can give you a definitive answer.

  • PrayinMama

Me an hubby have been threw hell and back with miscarriage after miscarriage… I took a test a few days ago with FMU and it came back inconclusive( must not have pee’d long enough but today I took one and it’s a faint but POSITIVE result… Last period was in June… I’m really hoping this is a good pregnancy and I carry to term with a healthy babes!!!

  • http://www.babyhopes.com/ Vickie B.

    It could be that the period is coming but the miscarriage has not actually happened fully yet.

  • http://www.babyhopes.com/ Vickie B.

    You shouldn’t have hcg still in your system after 4 months unless you were pregnant. It could be the digital tests are more sensitive than the lined one. I suggest that you try testing again in a couple of days to see if the tests show up differently. Yes, you can be fertile 4 months after birth especially if you aren’t exclusively breastfeeding.

  • Victoria white

    So im having a miscarriage?

  • Victoria white

    So im having a miscarriage without blood?

    That is something you need to discuss with your doctor.

    My last period started on May 23rd, 2014 and I haven’t had one since! I took a test today, and it was a positive! My boyfriend and I are very, very excited!
    However, the only thing that I am worried about is my existing health issues… I have a prolactin secreting pituitary brain tumor. I was diagnosed with it last year. I just hope that it doesn’t effect my pregnancy!

  • http://www.babyhopes.com/ Vickie B.

    Congratulations! As you have a diagnosed medical condition, you will want to get your doctors involved as soon as possible for your health and your baby’s health.

  • Amy

    Same is happening to me, I have Hashimoto’s, which also makes it difficult, but I got a positive yesterday (3 days before due period), 2 negatives today.

  • moanie14311

    I was due my period yesterday my last period was 2nd of July. I did a test tuesday night witch came up with a very faint second line, the other was a clear 2nd line. I went to the walk-in-centre this morning due to having brownish like discharge stuff that looked the same as I’d normally get before my period. Any how i gave the doctor a urine sample and she did a test there and it came up negative and couldn’t explain to me why the other two i took where positive. Shes suggested having a blood test done by my gp. She also said that this has happened before and the person had a positive back from having bloods took. I cant help but think she was just sayin that to reassure me but I’ve lost hope now. It really has broke my heart because we did tell close relatives :(

  • Steph

    I recently took an at home pregnancy and the line was very faint so I waited until the morning and took the other one from the box and still got the same faint line. I decided to wait a couple of days and test with a more expensive brand name of clear blue and it said i was pregnant and gave me a 1-2 week digital answer. The following day I went to the doctors to confirm since I am 2-3 days late on my period and the results came back negative. I am so confused I don’t understand how I could have gotten 3 false positives at home and a negative at the doctors…help explain please!?

  • http://www.babyhopes.com/ Vickie B.

    Unfortunately, you could have had an early miscarriage if your period did come fully on. If not, a blood test is definitely recommended.

  • http://www.babyhopes.com/ Vickie B.

    I don’t think you got a false positive. It could be that the level of hcg in your system is lower than what the blood test could detect. It’s also possible that the lab that tested your blood just did a bad job of the test. That does happen sometimes. Until you get your period or the pregnancy tests come back totally negative, I wouldn’t give up hope.

  • JG

    On Saturday, August 9th I took two Clear Blue digital tests and both came back as positive. On Sunday evening, August 10th, I took another digital test that came back negative. Thinking that I had a chemical pregnancy, I took just one more yesterday (August 11th) and it came back as “pregnant 1-2 weeks”. Then I took one more this morning (August 12th) and it came back as negative again. I thought these digital tests were supposed to be 99% accurate??? Anyone have any advice or experienced this before?

  • http://www.babyhopes.com/ Vickie B.

    It could be that the levels of hcg in your urine are on the very low level. The Sunday evening one could be that you had enough liquid in your system to dilute the hcg to a level that didn’t trigger the test. Are you testing before your period should have arrived?

  • JG

    Yes, all of these tests were before my period should have began. I usually have periods every 35 days, today is supposed to be the start of my new period – I’ve had just a tiny bit of spotting though so far…still feeling nauseous, slightly out of it, and with sore breasts. My nipples have also started changing (some strange goose-like bumps appeared). I had some bloodwork done yesterday and should hear back tomorrow. All of these test results have been like an emotional roller coaster!

  • Pip

    I have taken two home pregnancy tests that both said positive. I think I’m am due my period next week, but I am terrible at remembering these things. It might be this week. Everyone keeps telling me that it could just be elivated hormoan and not to get carried away. I definitely feel different but just very confused. Has anyone else experienced this?

    I’m about to take a pregnancy test. I was on birth control, but I have been off it for many weeks and I have not gotten my period. I just recently had a baby. She is three months. I wanted to wait to have anymore children. We definitely cannot afford another baby. But I don’t believe in abortion. I guess in the next hour we will see what God has in store for me:

    Typically, if you have a positive pregnancy test, you will be pregnant. You can’t have elevated hcg (the pregnancy hormone) unless you are pregnant.

  • kvanb

    I took two test which came out positive but when I took the doctor’s test at a teen clinic. I got a negative.
    Could the doctor be wrong?

  • http://www.babyhopes.com/ Vickie B.

    There are a couple of possibilities. 1) The lab who ran your blood test did a poor job. 2) Your hcg levels are extremely low and fall below a “positive” result for the lab. If this is the case, you should continue to have positive pregnancy tests. 3) You had an early miscarriage. If this is the case, the positive pregnancy tests will stop as the hcg clears your system.

  • hazel

    hello :) i got the same situation right now… my expected period was on aug.19 and now iam 7days delayed.. i took pt on the 3rd day missed period.. on the first sight it was neg. but in a few minutes later you will see a faint lines visible of our eyes.. on the 4th day missed period i took another pt and its neg. on the 5th day its same neg. me and my husband decided to go to the ob to make sure we unger go serum blood test and the test is neg. but the doc. says we wait until next week to be sure.. now my 7th day missed period i took a pt again and its neg. but to sign of having a period.. base on my experince this is the first time to be delayed like this since iam very sensitive on my period because i want to be pregnant.. before my period will come on the 3rd day missed.. do you think im pregnant??? plz help.. thanks

  • Samantha

    buy a clearblue pregnancy test the one with the words. its says pregnant or not pregnant. i believe it to be the most accurate one that I have found

  • Shyann Brandon

    i took three test and they all have a very faint line are they all three false positives also could having intercourse before taking the test mess with the results ? also i still have like 10 days before my period is even supposed to come

  • http://www.babyhopes.com/ Vickie B.

    That sounds really early to get a positive on a pregnancy test. What brand are you using? It sounds like it could be an evaporation line? Do you have normal 28 day cycles? If not, maybe you ovulated at a different time than you thought.

  • Bunny

    hi…. I have a big concern I was wanting to be a mom, and I took three pregnancy test all came back positive, my period was supposed to be here 10days ago and just now I got it…. does it mean that I lost my baby or that im not pregnant anymore, please help

  • http://www.babyhopes.com/ Vickie B.

    If you got the positive you should go see your doctor so they can confirm the pregnancy with a blood test. They will be able to monitor the hcg levels to make sure they are increasing like they should.

  • Samantha Gray

    I dont get it… 3 posititve and 4 negative pregnancy tests! Im having all the sympoms, ive had 3 kids so I do know them…. I had implant bleeding… I dont get it… im in tears, devastated. I went to the doctors and they took a blood test, and that came back negative for pregnancy and miscarriage. The doctor says it just might be too early! Why did I get 3 positive preg tests then? Please any responce will help?!? :-( :-)

  • http://www.babyhopes.com/ Vickie B.

    Are you testing with your first morning urine before drinking anything? If you get up in the middle of the night and drink water it can dilute your urine making the hcg concentration lower than the test threshold. Are you still getting positive tests?

  • Canadiangirl

    My husband and I have been trying for a while. I have been feeling different lately. I played hockey this past weekend and right after hockey I was spotting brown. I thought that was weird. Anyways, I took a a First Response Digits. Test at 1230 pm today and it came up positive. I went to the doctors and hour later and their cheap test came up negative. Then I bought a generic brand and took it 3 hrs later it came up negative. My husband wanted me to buy the First a Response test again so peed on it at 3am and it was negative. I am so confused. I have an appointment in a week with my doctor again to test. She thinks maybe I tested too soon after the positive. Help.

  • http://www.babyhopes.com/ Vickie B.

    It could be that you are at a very early stage of pregnancy. If that is the case, increased fluid intake will dilute the concentration of the hcg in your urine which could make a pregnancy test negative instead of positive. Test again after you haven’t had a lot to drink over the previous couple of hours. That will help the the hcg to become more concentrated.

  • Canadiangirl

    Thank you. I’m going to wait a few more days. I will try not to stress. Should I keep in mind that I am pregnant to illiviate the stress?

  • Concerned Citizen

    So, my wife and I have had two miscarriages this year. We’ve been trying again for a couple of months with no success. Our earlier pregnancies were conceived easily; after only a month or two. She took a test three days ago and had a faint positive line…excitement begins for the whole weekend. She took another test this morning and it came back negative, so tears begin. She had blood work done today and the hcg number came back at like 0 or less than 1.

    What’s this mean? Is there a chance she’s still pregnant, or was it a false positive?

    Facts:
    -She is supposed to “start” today, and she’s very regular.
    -All the right symptoms; inflated/sore boobs, nips look a little different, a little nauseous and dizzy feeling at certain times.
    -The test three days ago was done using blood on a pee test…it’s worked before and it showed up positive this time.
    -Test #2 was urine and showed up negative.
    -hcg test showed up “less than 1″

    Do I have anything to look forward to, or is hope lost? It gets discouraging, and I can’t help but wonder what’s going on. An answer from someone would be great.

  • http://www.babyhopes.com/ Vickie B.

    I am sorry to hear that you are having such a hard time staying pregnant :( Unfortunately, based on the info you provided, it sounds like there was another miscarriage. Is your wife under medical care for her recurrent miscarriages? If not, you might want to try some herbal supplements to level out her hormonal levels so you can sustain a pregnancy past the very early stages.

  • Svetlana

    I think I am pregnant- I have a stuffy nose for 2 weeks now! I get tired( no patience) and sometimes a bit nauseous. Also, been having cramps on the lower left side. My cycle is never regular! But I took an ovulation kit and was showing that I had an ovulation on Sept. 27th and 28th. We did the deed on 27th and 30 days have passed and no period yet. I took a test but it wasn’t a morning pee and I did drink tea about an hour prior and it came out negative. Do you think its a false test and that maybe I should try in a week or so?

  • http://www.babyhopes.com/ Vickie B.

    You should try testing again with first morning urine. Unfortunately, due to the fact that you don’t have regular cycles, it is tough to say if the delay in getting your period is due to being pregnant or just your wonky cycle.

  • Not Sure

    I see in several comments that blood results don’t seem to be same day? Is there an average waiting time for getting them back? I took an at home test and I think it is positive, but am not sure as I have a thyroid problem and previously when my thyroid was out of wack my breasts were sore and produced milky fluid which the Dr. said was due to the thyroid messing with other hormone levels. I am making an appointment tomorrow for a blood test but my fiance is out of town and I don’t know if I should say anything until the blood test comes back as we were not planning a child right now. But I also don’t want to wait a week for confirmation. I am mostly wondering if there is any way that it is a false positive. Any help is appreciated.

  • http://www.babyhopes.com/ Vickie B.

    You can call your doctor to find out how long it usually takes to get blood test results back. My guess is that it varies from doctor to doctor. Thyroid problems will not result in a positive pregnancy test.

    Thank you

    Thanks for the response. I don’t know if it was technically a miscarriage, or if it was just a fluke. The line was faint, very faint actually.

    She is RH- and her doctor told her that he’d put her on Progesterone and also she’s to take a baby Asprin every day when she gets another positive test. I think she might have jumped the gun on this one a little. She started her period a day or two after I posted this, so it’s definitely over…whether it was an early m/c or if it was just a false positive. We’re going to just keep doing our thing and see what turns up. We’ll stop “trying” so hard and just let nature do its thing. If it’s meant to be, it’ll be.

    Thanks again for the input. I was out of my element posting something on here for the public, but I like when strangers help each other; hard to find people who want to help someone without it benefiting them these days.

    Hi I did 2 normal pregnancy tests which were positive. Then did 2 clear blue digital which said pregnant 2-3. I then did another clear blue which said pregnant1-2. Today I still couldn’t quite believe it so I brought another test which came up not pregnant?? I went to the clinic and they did a test which came up positive but she said it was faint so most likely very early and to test again in a week? Anyone else had this and had a positive outcome? Thanks

    So, I am seriously confused. On Sat. I took 3 hpts… all at different times of the day. One with FMU, one at 3 in the afternoon and one at 11:15 at night. All three came back positive. Monday morning I took another one and it was positive. I was a bit paranoid and took another one Monday night and it was negative. I took three more this morning (all with FMU on Tuesday) and all three came back negative. Now this is where I am seriously confused. I still have not received AF. No sign of it coming for me. I have tender nipples (not the whole breast). I have no idea if I am pregnant or not. Anyone have any advice?

    If you are in the very early pregnant stage, the level of hcg in your system will vary widely depending on how much liquid you have been consuming. As the pregnancy progresses the level of pregnancy hormone will be much higher so all the tests should stay positive at all times. Good Luck!

    In the early stages of pregnancy, your fluid intake can cause your results to vary widely. As much as I hate to say this, sometimes what you are experiencing could be an indication of a very early miscarriage. Keep testing to see if the test stay consistently positive and schedule a visit with your doctor.

    2 days ago my wife was period then she said she was not period today n take the pregnancy test it show show two line.could be my wife pregnant

  • http://www.babyhopes.com/ Vickie B.

    If the pregnancy test showed two lines, that typically means that your wife is pregnant. She could have been experiencing early pregnancy bleeding. It would be wise to have her see her doctor to confirm the pregnancy and to monitor the bleeding.

  • Ellie

    Im ten days late. So i decided to take a test well i eneded taking 6. I haf 4 from the doc which were a faint positive and i had two digital that came yes. My question is there anyway this could be a negitive positive. My doc is making me go for blood hcg test. And im wondering if it was negitive i would have at least one negitive right?

  • http://www.babyhopes.com/ Vickie B.

    If all of them are showing a positive, then it would appear that you are pregnant. The blood test will tell show how much hcg is there and they will be able to confirm that you are pregnant.

  • Cruz

    I took two at home test and got positive on both. A week later went to a clinic and was positive again. But that was t a blood test. Now 2 months later I’m having period like symptoms and I’m worried and sad.

  • http://www.babyhopes.com/ Vickie B.

    Are you actually bleeding? What type of symptoms are you having? Your hormones will fluctuate dramatically with pregnancy so the symptoms you are having could be just related to your pregnancy progressing. If you are concerned, you should contact your doctor.

  • emily

  • Lindsey

    Hi, I haven’t had my period now for 2.5 months. I have PCOS, and so my periods have always been irregular, but I have never gone 2 months without my period. My breasts felt swollen and my nipple became sensitive. I am 31 years old and took a HPT this morning, FMU and the test was positive. I purposely chose a test that had a distinct difference between positive and negative so I wouldn’t be confused. I am going to take another test tomorrow and if that is positive, will go to the doctor. My worry is, I was always told I would have issues conciving and now all of I sudden I may be pregnant? Any advice would be helpful

  • http://www.babyhopes.com/ Vickie B.

    It could be that you caught the pregnancy at a very early stage. If you continue getting positive pregnancy tests with your first morning urine, I would go back to the doctor and tell them to do another blood test because your tests are still coming back positive.

  • http://www.babyhopes.com/ Vickie B.

    Having PCOS doesn’t mean you will never get pregnant, just that is can be a lot more difficult to get there. If you get another positive definitely go talk to your doctor about it. Hopefully you will get another positive tomorrow!

  • EloiseLee

    I got a positive pregnancy test, then later in the same day, started my period. not an e-vap line (it had color), and I read the test within 3 minutes. It was positive. I’m worried :/

  • http://www.babyhopes.com/ Vickie B.

    This was posted about a week ago? You should know now if it you were just having early pregnancy bleeding or an early miscarriage :( I have my fingers crossed that it was just early pregnancy bleeding and that everything is okay.

  • Ytalia

    Hello, my period hasn’t been on for almost six weeks but and I’ve taken two pregnancy tests both were negative. I have two children and found out both times that I was pregnant in the third or fourth month could I be pregnant this time and the pregnancy test not pick it up? I’ve had no luck finding answers.

  • kat27

    My period is due on Wednesday of this week (today is Tuesday). Beginning late saturday/early sunday, I started getting some spotting, brownish”blood.” nothing major. I have taken 5 HPT.. 1 (Rexall brand, blue dye) said negative at first (within the 3 minute time frame), then switched to a very clear “positive” after about 25 minutes. Since then I have taken 4 more; all of which have been very clearly negative. The first 3 were Dollar General “baby” HPT, (taken sunday afternoon, Monday morning, and Monday afternoon…after 4 hours without drinking/urinating) and Then this morning I took the ClearBlue Digital with FMU, it came up negative (“not pregnant”). Thoughts? Btw- I am 100-95% accurate with my birth control- taken for 10 years, same time of day, NEVER missed a pill.

  • Holly M Dobbins

    I have had my tubes tied for about 5 years now. I have all the symptoms of being pregnant. Went and saw a doctor he said I was but did an ultrasound and couldn’t find the baby but did find fluid. The nurse check the test again and said it’s a false positive. I’m tired all the time, Nassau, heart burn, pressure on my stomach and back alot, get car sickness, and haven’t had a period for a month now. What is going on with me?

  • http://www.babyhopes.com/ Vickie B.

    Ultimately if you have a history of not getting positive pregnancy tests, then yes you being pregnant is a possibility if you had unprotected sex. You need to discuss this with your doctor to see what she says.

  • http://www.babyhopes.com/ Vickie B.

    If the majority of tests were negative, I would lean more in that direction especially since you have been on birth control for so long. 4 days have passed so hopefully your period arrived.

  • http://www.babyhopes.com/ Vickie B.

    Unfortunately, this is something you need to discuss with your doctor. As they did the ultrasound and didn’t find a fetus, it is highly unlikely that pregnancy is the cause of what you are experiencing. The doctor should be able to help figure out why you are feeling the way you are feeling.

  • gel

    I have the same case as you. I have PCOS and I also have retroverted uterus. I have had HPT came out positive. I will have blood test and urine test tomorrow to further confirm if im pregnant. My worry is that I have been having cramps on my lower abdomen and lower back coupled with dizziness. I am praying that the tests tomorrow will come out good because my fiance and I really would like to start a family soon since i am already turning 33 next year.

  • Lindsey

    Awe, best of luck to you! Well wishes being sent your way. At the time I had posted this, I wasn’t sure if I was In fact pregnant, and when I had gone to planned parenthood to confirm, I learned that I was really pregnant. A lot farther along than I expected to be. I then learned I was 12.5 weeks! I never would of thought that, nor had I EVER thought I would be able to become pregnant. Complete shock to me. Let me know how you turn out :)

  • http://www.babyhopes.com/ Vickie B.

    Congratulations on your pregnancy! Here’s to a happy, healthy almost 6 months left! :D

  • Stacy

    I took a clear blue easy digital pt last night after work and it was a positive, but I took an off brand test this morning before work and it was negative, could last night’s test be a false positive?

  • http://www.babyhopes.com/ Vickie B.

    It’s not likely. Clearblue are pretty reliable tests. What probably happened is that the off brand one wasn’t as sensitive at the Clearblue. Did you test before your period was due?

  • Stacy

    yes I did test prior to my period by 3 days. My stomach was upset yesterday and I had a funny feeling just like I did when I found out I was pregnant with my first child. That is why I tested early.

  • Stacy

    What do you suggest I do? Wait till the weekend and try the test again? We have been trying for a few months and well…we got pregnant so fast the first time I thought it was going to be that easy again and it just hasn’t been and I am a bit anxious.

  • http://www.babyhopes.com/ Vickie B.

    :) It depends on what pregnancy tests you have. If you have a brand name like Clearblue or First Response, they will most likely give you an accurate result right now. If you still have the off brand ones, they may take a little while to show the positive. It would seem that you are probably pregnant :D All you need is the confirmation from another test!

  • Jamie

    I took 2 pregnacy tests that said I was positive. I did a urine sample for my doctor and said it was negative. I was detested. I decided to do another test and it still came out positive.

  • http://www.babyhopes.com/ Vickie B.

    If it is early in your pregnancy, chances are you had something to drink before going to the doctor’s office. The extra fluid could have diluted the small amount of hcg that was in your urine and that would make the test not show a positive. My suggestion is to take another test in a day or two and if it is positive, schedule another doctor’s visit and don’t drink anything before going.

  • Dee

    Hi Well Over The Last Couple Of Weeks I Have Taken 7 Pregnancy test 2 of which were clear blues all came back positive and 3+ weeks I’ve been throwing up allot and didn’t have a period last month but i see no changes in my stomach and just don’t think I’m pregnant cause I’ve been trying for years could i be having a psychological pregnancy ?!!

  • Jenna

    Hi, I took two home pregnancy tests and they both said positive but when I went to the doctor, twice as well, they said it was negative. Any help on why this is?

  • Jennygrrl

    Hi there, My period came on October 26th. Was intimate on November 8 & 11. Period was then 5 days late but showed up on Nov. 29. It lasted about 2.5 days. I took 2 HPTs on Dec. 9 and they were both positive. Went to Dr. and had a blood serum test and it shows my HCG level as very low (210) Going for a pelvic ultraound tomorrow and freaking out right now. Any insight from anyone?

  • Diane

    So my last period was on November 8 and it has been pretty regular for the past few months and my period was due December 11 As of today December 15 I still have no period but I do have cramps backache, dizziness and my Breast are really sore and I’m also bloated ,I tested December 14 at 8 with a early result pregnancy test from target and it came back positive so I tested December 15 with dollar tree test at 3 and came back negative what can be happening?? Help anyone ?

  • http://www.babyhopes.com/ Vickie B.

    If you have taken 7 pregnancy test that have all been positive, then you are most likely pregnant. Go see your doctor.

  • http://www.babyhopes.com/ Vickie B.

    Have you taken another home pregnancy test yet? It could be that the blood test was done too early. If you take another pregnancy test now and it is positive, then I’d head back to the doctor and get another blood test.

  • http://www.babyhopes.com/ Vickie B.

    :( Sounds scary for you. Hopefully the doctor will see a healthy fetus when you get your ultrasound.

  • http://www.babyhopes.com/ Vickie B.

    The one in the afternoon could have been skewed if you had been drinking a lot of liquid before that point. Stick with first morning urine because it is more concentrated. I’d head to the doctor for a blood test if you take another test and it is positive.

  • Ana

    Hi, My period was due on 4th Dec but as I suffered a lot of cramps and breast swelling , I took test on 3rd Dec which was positive. I did 2 tests one in the morning (not first pee) and other one same evening both came as positive. I did Test again today ( not first pee) after 2 weeks wait and it is negative. For last 2 weeks I am suffering from sore breasts, cramps and serious acidity issue. I never had any bleeding. Does it mean the tests earlier were false.

  • http://www.babyhopes.com/ Vickie B.

    Did you go and get a blood test? The first tests would be accurate as they all were detecting hcg in your urine. What could be happening now is your hcg levels are very high and the tests are unable to register them, or you could have had too much liquid that diluted your urine to a level that was below the pregnancy test sensitivity. You really need to go and see your doctor to get your confirmation.
