How Long After Ovulation Can You Take A Pregnancy Test?



Pregnancy Test

When you’re trying to conceive, waiting to take a pregnancy test is no easy task. Of course, there is a lot of appeal when it comes to testing early; however, it’s always best to wait until the day after your period should have arrived before testing. One of the benefits of waiting until this point is that you can take almost any pregnancy test and receive an accurate result. Of course, testing too soon can result in a false negative test and mean that you must wait to test again anyways.

It is important to remember that it takes time for a fertilized egg to become implanted within the uterine wall. The length of time that this takes can differ depending on your body since no two women are alike. According to research, about 85% of pregnancies start producing hCG at some point between eight and ten days after ovulation. The sensitivity of the pregnancy test that you’re using also plays a role in how accurate of a result you get. As a result, you might have to wait a few days after this initial eight to ten day period to receive a positive pregnancy test if pregnant.

If you’re looking for a more accurate option, making an appointment with your health care provider for a clinical blood or urine test will generally provide you accurate results. The blood test can detect pregnancy as early as 24 hours following implantation, which is about nine days after ovulation has occurred. The accuracy is variable though depending on the lab your doctor uses and what level of hCG is considered a positive result. It is important to note that these tests are often expensive and inconvenient. As a result, women often choose to settle for home pregnancy tests.

Home pregnancy tests work by measuring the level of human chorionic gonadotropin (hCG) present in a woman’s system. As a pregnancy progresses, amounts of hCG will increase as well. For instance, hCG levels will typically be around 25 mIU 10 days after ovulation. In a healthy pregnancy, hCG levels are expected to double ever 48 to 72 hours. By using a test with a sensitivity level of 25 mIU, you can detect pregnancy 10 to 11 days after ovulation. Tests with higher sensitivities, for example 100 mIU, will require you to wait until closer to your period due date for a positive result.

Another important factor to keep in mind is that the rate of hCG will vary from woman to woman. This means that some pregnancy tests might detect pregnancies in other women earlier than it will for you. If you test too early with a highly sensitive test, there is a fair chance that you will have a false negative test as a result. If this occurs, it is best to follow up with additional testing after a few days have passed.

    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.

    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!

    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

    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.

    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.
