When a couple is trying to get pregnant, having to wait to find out whether or not you have conceived a child can be quite challenging. In fact, if you’re like most women, you would probably like to know the exact moment that conception occurs.

Unfortunately, accurately detecting a pregnancy can only happen so soon after conception. There are many women who will take a test early hoping to get a positive determination that they are pregnant. However, this generally only leads to inaccurate results. This is still the case even with the production of more highly sensitive early pregnancy tests.

The best time to take a pregnancy test will always be after you have missed your period. Regardless of what test you take at this point, you will always have more accurate results because you have given your body enough time to secrete high enough levels of human chorionic gonadotropin, or hCG, to make a positive determination.

So, while taking a test early is tempting, waiting is your best shot at receiving accurate results. However, if you take a test and it comes back negative, don’t lose hope. There is always a chance that you are pregnant and a test is just not showing it yet. The only point at which you can be absolutely positive that you aren’t pregnant is after period arrives.

Understand That Detecting Pregnancy Will Vary From Woman to Woman

One of the most important ideas to remember when you’re trying to get pregnant is that you’re unlike any other woman when it comes to your body and its processes. There are many common misconceptions regarding how soon you can detect pregnancy and there is a sizeable number of women who fall victim to this notion.

After conception occurs, there is typically a 7 to 10 day period before the fertilized egg is firmly implanted in your uterus. At this point, your hCG levels will begin to increase which is essential for making a positive confirmation that you’re pregnant. As you can imagine, this entire process can be lengthy. However, it is the best way to see if you are actually pregnant.

Understand How a Pregnancy Test Works to Guarantee Accurate Results

Of course, if you aren’t taking a pregnancy test properly, there is a high likelihood that you will receive inaccurate results as well. So, before you begin thinking about when to take your pregnancy test, it’s important to understand how it works.

Any pregnancy test that you take is measuring the level of hCG in your system. As your pregnancy continues, the level of hCG is expected to steadily increase. As a frame of reference, most women have an hCG measurement of 25 mIU 10 days after ovulation, 50 mIU once 12 days have passed since ovulation, and 100 mIU around two weeks after ovulation has occurred.

Of course, different tests and brands of tests will have different sensitivities to hCG levels within the body. So, if you take a test that requires a hCG concentration of 100 mIU and your body is only at a hCG measurement 75 mIU, you can expect a negative result although you might be pregnant. Therefore, it’s important to be aware of all of these factors prior to taking a pregnancy test.

    I don’t understand why it’s important to wait past the period due date? If you conceive but your period isn’t for another 2 weeks, cant you still get accurate results before a period is missed due to the hormone increasing over those weeks?

  • Vickie B.

    You can take the tests earlier. For the most accurate results, waiting for when your period is due is best. Many of the tests on the market today advertise that you can accurately (so they say) test about 4 days before your period is due.

    I think and hoping I’m pregnant, so I took a pregnancy test today but my period isn’t for another two weeks and so it came out negative. Mind, I did this before reading about the “too early or else” facts. I have hope now that I am and have too be patience for my next hpt

  • Vickie B.

    You definitely took it too early. Actually, two weeks before is when you would normally be ovulating and having sex to get pregnant. It sounds like your timing could be off.

    I tries the famous thing our obgyn tell us to do to get pregnant . Have intercouse the three days after two week of the first day of your period I took a pregnancy test today one day before my missed period . And it came out negative do you think I should wait like my dr. Told me to after two weeks of my missed period is when I should take a pregnancy test.

    I think people are confused because you used “ovulation” rather than conception regarding HCG levels to rise. Ladies do a preg. test every two weeks if u can afford it then see if you miss your period. If u miss your period it is likely that you will be devorced within 1 year!

  • Ally

    You can only get pregnant in a small window during your cycle, when you ovulate, and (assuming your body is prepared to carry a pregnancy) that can be as little as ten or as much as 16 days before your period. So if your period isn’t due for another two weeks, you have either only just ovulated or you haven’t ovulated yet, and no fertilized egg (if there is one) has had a chance to implant, so even if you do conceive this cycle, your body is not producing the hormone yet that a pregnancy test looks for.

    I keep track of my periods very well and have consistently had my period around the same time every month. However this month I had a little bit of faint pink spotting one day about a week before my period I took a pregnancy test three days before my period normally would have been and it was negative. However I am now a week past my period due date and have had no spotting or cramping of any sort. should I take another test? Or could it still be too soon

  • Vickie B.

    If you are relatively regular and you are late by your record keeping, I’d say a pregnancy test is definitely in order :)

  • Rachel

    I found out that i was pregnant 3 months but i only missed a period once.For the two months i had a normal period.Is it possible to have a period during pregnancy.Am totally confused.

  • Vickie B.

    Did you ask your doctor about this? I do know that some women apparently bleed, like a period for a good part of their pregnancy so maybe that is what is going on with you. Congratulations on the pregnancy!

  • Julia Price’Banks

    Look. We had sex on the 1st and 2nd tryingto concieve. My period is due on the 14th and im feeling very strong nausea. Is it too early cause we really wanna knoe.the 14

  • Courtney

    I took a pregnancy test 5 days before my missed period, and it came out positive! Should I take another one in a few days anyway to make sure?

  • Vickie B.

    It’s possible. You can start testing with a pregnancy test on the 10th or the 11th.

  • Vickie B.

    The pregnancy tests on the market today typically can pick up pregnancies about the time you got your positive result. :) Congratulations!

  • Lord help us all

    Dear God I hope your kids have better grammar!

    Bless you and I hope you are. As far the other two of you that replied, you should be ashamed of yourself. I am sure you are not perfect.

  • Jackie

    I had intercourse the day before my period was supposed to come and now, a week later, I still have not gotten my period. It usually comes pretty regularly. Is it possible I can be pregnant? Is it too soon to take a test?

  • Vickie B.

    You would not have gotten pregnant if you has sex right before your period was due. If you had unprotected sex at other times of the month, they might have caused you to get pregnant.
