Taking Pregnancy Test After Conception


When Can I Take A Pregnancy Test?

When you are trying to get pregnant, having to wait to find out if you have conceived is challenging.   If you’re like most women, you would probably like to know the exact moment that you conceived and  take a pregnancy test right away!

Unfortunately, accurately detecting a pregnancy takes a bit of time. There are many women who will take a test early hoping to get a positive result that they are pregnant. However, this generally only leads to inaccurate and disappointing results. Even when using the very sensitive pregnancy tests on the market today, you still need to give your body time to start producing the pregnancy hormone.

The best time to take a pregnancy test will always be after you have missed your period.   Even the least sensitive pregnancy tests  will give you more accurate at this point.  By the time your period is due, you will have given your body enough time to produce enough hCG to register as a positive result on the pregnancy test.

So, while taking a test early is tempting, waiting is your best if you want accurate results. However, if you take a test early 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.


How Long It Takes To Get A Positive Pregnancy Test Will Vary From Woman to Woman

When you are trying to get pregnant, it is important to remember that every woman’s body is different.   Due to variations in cycle length and travel time to implantation,  the number of days for a positive pregnancy test to appear will vary.

Your body does not start producing hCG the moment that conception occurs. It usually takes between 7 to 10 day period for the fertilized egg to implanted in your uterus. You will not be able to detect pregnancy before implantation happens, because there will be no hcG to detect. Once implantation occurs, your hCG levels will begin to rise. You will need to wait an additional 2 to 3 days before you *might* be able to get a positive pregnancy test.  Unless you have implantation bleeding, it is going to be hard to gauge how early to test.  If you have a 28 day cycle, on average, you will ovulate on day 14. If it takes the full 10 days for your fertilized egg to implant, then testing 1 or 2 days before your period is due could have accurate results.

hCG Levels and Getting Accurate Results with Pregnancy Tests

If you aren’t taking a pregnancy test properly, there is a high likelihood that you will receive inaccurate results. Before you take your pregnancy test, be sure to fully read and follow the instructions included with the test.  Failure to do so could end up with inconclusive results which means you will have to spend more money for another test.   Testing with your first morning urine is recommended for the most accurate results.  If you test during the day, be sure to limit fluids you are drinking to help the hCG in your urine get as concentrated as possible.

Any pregnancy test that you take is measuring the level of hCG in your urine. Your level of hCG will  is expected to steadily increase. Most pregnant women have an hCG measurement of 25 mIU 10 days past ovulation (dpo), 50 mIU 12 dpo, and 100 mIU around 14 days past ovulation.

Different pregnancy brands of pregnancy tests will have different sensitivities to hCG levels within the body.  If the level of hCG in your urine is 75 mIU (definitely pregnant!) and your test detects 100 mIU, you will get a negative result.   If you are testing before your period is late, you will want to test with a pregnancy test that is at the 25 mIU level or lower.
