How Long After Ovulation Can You Take A Pregnancy Test?



Excited, happy woman in bathroom viewing pregnancy test

You are tracking your cycle and you know when you ovulated. You timed the baby making sex perfectly. You’ve got all fingers and toes crossed that this time will be THE time. Now comes the torturous wait to take the pregnancy test.

Yes, you’ve heard from all the sources that it is always best to wait until you’ve actually missed your period to take a pregnancy test, but you also know that most of the tests on the market say you can test before that point and you NEED to know right now!

Many women start testing way too early in their eagerness to know. Doing that can line you up for disappointment and false negative results. You will have to spend more money and endure more stress when you have to test again.

 

Don’t Take a Pregnancy Test Too Soon

It is important to remember that it takes time for your fertilized egg to become implanted in your uterine wall. The time frame varies from woman to woman, but research shows that 85% of pregnancies start producing hCG between 8 and 10 days after ovulation. The pregnancy hormone (hCG) level will start out very low after implantation and will double every 2 to 3 days.

For example:

Let’s say your fertilized egg implanted at 8 days past ovulation (dpo). If you have a normal 28 day cycle, that will be 6 days before your period is due. Maybe by the end of the day, your hCG level is at 5 mIU.

If you wait two days (4 days before your period), your hCG level should be around 10 mIU. Depending on the sensitivity of the pregnancy test you are using, you might be able to get a very light positive result at this point. It’s not likely, but it is possible.





If you were able to wait two more days (2 days before your period), your hCG levels would be around 20 mIU. Your chances of getting a distinct positive result is much better at this point. Most of the pregnancy tests available today are able to detect at around 20 – 25 mIU of hCG.

Not every woman will get results this early. If you happen to have a slow moving fertilized egg that doesn’t implant until 10 DPO, you will not get a positive result until closer to when your period is due.

Also, the doubling rate of the hCG is a variable. The hCG typically doubles every 2 to 3 days. If your hCG is doubling more slowly, a positive result will not show up until later.

So, When Should I Take A Pregnancy Test?

Unless you are a glutton for punishment and have a large disposable income, waiting until 2 or 3 days before your period is due or 11 or 12 days past ovulation to test would be a good option. But know, a negative result at that point does not mean you are not pregnant. It could be that you are still testing too early based on when your baby implanted and how fast the hCG is doubling.

If you can hold out and wait until AFTER your period was supposed to start, you will get the most reliable results at this point.

Blood Based Pregnancy Tests

If you just can’t wait, you might be able to get quicker results by visiting your doctor for a blood test. Blood tests will measure the hCG in your blood so it bypasses the possibility that your urine is not as concentrated as it needs to be to produce a positive pregnancy test result. That morning coffee and other liquids may contribute to false negative results very early on in your pregnancy.

Depending on the lab, a positive result will be between 5 mIU and 25 mIU of hCG in the blood sample. If the result is at the lower end of a positive result, you will likely have to go back and get another blood test just to make sure the amount is going up.

The accuracy is variable though depending on the lab your doctor uses and what level of hCG is considered a positive result.

    My husband and I are actively trying to get pregnant. I have been using ovulation tests to track my ovalulation. I got a positive ovulation last wednesday, which means I ovulated on day 19-21 of my cycle. I had some light brown spotting today. If I successfully conceived it would have been last Wed or Thursday. Could this be implantation bleeding and when should I plan to tale a home pregnancy test? Thank you in advance for any advice!

    This information seems very old, and is inaccurate. You can get home tests that will detect as low as 10miu. This lower threshold for miu allows you to test MUCH sooner, getting an accurate result as early as 8dpo (though some women don’t build up to 10miu until day 10 or later, so if you want to test early and get a negative, I’d retest to be safe, since they are cheap!).
    They are INEXPENSIVE (I got 10 tests for under $14), so you can start testing on day 8, and don’t feel bad about testing everyday for the next week in case you are anxious.

    Wondfo pregnancy test 10 miu, I got mine on Amazon.

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

    Wondfo tests are not 10miu. They are 25miu. There are 10miu tests but our experience has shown them to be variable in results.

  • KeepinBlitzesAway

    Wondfo offers both 10miu AND 25miu.
    Would love links to any info you have on clinical trials. thanks!

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

    What’s the url to an amazon listing where Wondfo sells the 10miu? We sell the wondfo brand on this website and they didn’t have 10miu when we ordered wholesale from them. We used to sell the 10miu tests and we received way too many complaints about them not working as they should have – negative results when people are definitely pregnant. They did work for the majority but we were never able to really figure out why the results were not consistent across all users.

    My window of ovulation was the 4-6 of oct. Which I stopped bc the period before. I have had cramps headaches.peeing more. Moody and 6 days late on my period. But I took a hpt and it came out neg today.(18days after intercorse) could I be pregnant or. Is the neg test probly righr?

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

    It’s hard to say, unfortunately. The first months of coming off hormonal birth control can really mess with what was originally a normally occurring cycle.

  • wanttobemommie

    I was on the nuva ring. Which does jot go thru your blood system. So I was told there would be no with draw symptoms. And it been about 3 weeks and my boobs are hurting more and more. Im peeing more and more. And I been cramping 3 weeks now. Took 3 test one each week and all neg. But I have pcos and thyroid problems. So idk is a pee test would work at onlt 3 weeks

  • Samantha H

    My period was sept 12 and we had unprotected sex randomly all month. That was my first period off of my iud. Took two pg tests today and neg. waiting til my period decides to show up or not. Thinking about testing in a week again, do you think I could be preggers? I’m hoping so!

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

    The nuvaring can cause hormonal imbalances when you stop using it. It can take your system a little while to get back to normal. The only way to know if you are pregnant or not is for a positive pregnancy test or for your period to come.

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

    It really depends on the type of iud you were using. Some IUD’s use low dose hormones which alter your hormonal imbalance. If you were using one of those it can take a while your your system to get back to normal.

  • Samantha H

    Thank you for getting back to me:) I’m not pregnant this month and you are right! I went to my dr and she said the same thing to me about the iud. It took me about three months to get pregnant with my son after we took out my first iud.

  • Gemma

    Hi I have PCOS and been trying for a baby for a few years, dont have regular cycles but have come on 35-37 last 2months. we have had clomid treatment once in December and blood tests showed I ovulated..was unable to make next appointment so done a home ovulation test day 21 and came back positive. Anyone know how reliable these are with PCOS or was I likely to have a false positive ovulation result? Or with PCOS could it say im ovulating but im not actually producing a suitable egg? Any help please?

  • Hopeful, but Anxious!

    Hi! I have been TTC for over 2 years and have just finished my first cycle of Clomid this month. I took it on days 5-9, which was the 9th-13th. I used the opk’s up through the 23rd (stopped only because I ran out, and understood ovulation was to occur generally between the 5th and 10th days after last dose). Ultimately, I didn’t have a positive kit result at all, but assumed that maybe I missed the window because I only tested twice a day over a couple of days, and in the past I’ve had very short windows where the hormones show up (using the opk’s). I’m wondering if its at all possible to ovulate much later during one’s cycle on clomid? I typically ovulate between the 11th and 13th day of my 28-day cycle. I’m wondering because I’ve been super dry-no detectable cervical mucus until a couple of days ago, and today (Feb 28th) was the first day it was very slippery/eggwhite consistency (sorry about possible TMI!). The last time we tried was on Sunday (the 23rd, and 10th day after finishing Clomid). Now I’m wondering if its at all possible to be just ovulating now, with the husband gone all day?! Ugh…so anxious!

  • Amy Lyrock

    I had my copper based iud taken out last month and we had sex 2 weeks straight through ovulation and everything. I have sore breasts, nausea, every symptom from my prior pregnancies except a positive test. I am not suppose to start until Wednesday I feel pregnant. What do you think my chances are? I have never had a problem conceiving before.

  • curious mind

    Please help me …
    I took to pregnancy test the sametime just now. One digital and one with the lines …. the digital one said no and the one with the lines had 2 line but one was very faint but i can see it ….. my period suppose to come one the 17th …. but i have every pregnancy symptom so thats y i checked. But which test is accurate

  • curious mind

    Should i take another test?

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

    It could be that you have a low level of hcg in your system and the digital test did not pick up on it. Test again in a day or two, first thing in the morning before drinking anything. If you are pregnant, you should get a darker, more prominent test line.

  • nikki

    Hi I am 44 and going through menopause and it been 2yrs since I had my period can I still get pregnant

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

    If you haven’t had a period for that long, chances are you are menopausal which means you will not be able to get pregnant. To be sure though, you should talk to your doctor and have them test your hormones. They will be able to say whether or not you are truly menopausal.

  • Kimberlee

  • Guest

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

    Until your period arrives, there is a chance that you are pregnant. If your period does not arrive and the tests keep coming back negative, you might want to contact your doctor to find out what is going on.

  • idontunderstand

    I don’t understand why my test why my test was negitive. I had intercorse three times during my fertile days last time was 2 days before ovulating. We didn’t use protection and he didn’t pull out all three times(trying to conceive) but I took a clear blue 4days before period test, I took the test two days before expected period. But I did my research so we could conceive makes no sense that I’m not pregnant. Help !! Why would my test be negitive I am 23 too so healthy age

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

    You have to realize that even with perfect timing, it can take time. It is a game of percentages:

    30 percent get pregnant within the first cycle (about one month)

    59 percent get pregnant within three cycles (about three months)

    80 percent get pregnant within six cycles (about six months)

    85 percent get pregnant within 12 cycles (about one year)

    If you drink, smoke, use drugs, are over/under weight, then you will be negatively impacting your chances of getting pregnant as well. Are you using ovulation tests to confirm that you are actually ovulating when you think you are?

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

    You could probably test in a day or two and get accurate results.

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

    Vitex is an herb. Not something your doctor needs to prescribe. You can typically get it at a health food store. (At least you do in the United States. I am not sure how you would get it living in India.)
