How Soon Can You Take a Pregnancy Test? Consider All the Options

Every woman wants to quickly confirm the fact of conception. For this purpose doctors recommend to do a pregnancy test used to confirm pregnancy in the early stages. Such tests react to the content of a particular hormone – HCG (human chorionic gonadotropin). But is it possible to get the clear results?

HCG is produced in scanty numbers, even in non-pregnant women. But soon after fertilization its amount starts to increase rapidly. By creating a reagent that is capable of responding to the presence of HCG in the urine of women, scientists have made a huge step forward. Now any woman can define a pregnancy at home. But in order to get reliable results, you must follow the instructions given therein. In particular, you should know how many days after intercourse you can do a pregnancy test and does it necessary to do a test after a delay of menstruation.

How many days should pass to do a pregnancy test after unprotected intercourse

Thus, a pregnancy test contains a reagent that is manifested in the form of a second strip if HCG is present in the tested urine – if a woman is pregnant. But this requires that the amount of HCG has had time to grow to a certain level at the time of the test. For this reason, you can get a false negative results at too early testing. So, do not rush, otherwise the test will not show pregnancy.

How many days should pass to do a pregnancy test after unprotected intercourse

There are only a few days in each menstrual cycle, when there is a chance of getting pregnant. If unsafe or insecurely protected sexual intercourse took place in the period of ovulation, it makes sense to carry out a pregnancy test not earlier than 10 days after sex. It will be more accurate 14 or more days after.

The fact is that the HCG begins to produce only from the time of implantation of the ovum in the uterus 5-7, and sometimes after 10-12 days after intercourse. In the first day after fixing the egg in the uterus the amount of HCG is still too little for the test to identify him. This is only possible in a few days after implantation.

When to do a pregnancy test with a different sensitivity: before or after a delay

The minimal concentration of gonadotropin in the urine, which a pregnancy test is able to determine is 10 mIU / ml. These are hypersensitive tests that can be carried out before the delay of menstruation. Tests with a sensitivity of 10 mIU / mL or 15 mIU / mL are able to show a pregnancy 10-12 days after ovulation (in some cases even after 7 days from the moment of conception) – a few days before the anticipated start of period.

Pregnancy tests with a different sensitivity

A pregnancy test with a sensitivity of 20-25 mIU / ml depends on a day of doing such a test. The indicated concentrations of HCG in the urine reaches only after 2 or more weeks from conception. That is why, the results of such tests can be considered valid only if they are carrying out in the second or third day of delay. If you want to get the most truthful result, you should do a pregnancy test not earlier than on 5th day of delay. The research results show that test held in the first day of delay indicate the presence of a real pregnancy only in 16% of the cases, despite the encouraging promises of manufacturers.

All cited figures and dates are rather conventional. In each case, the difference may be a few days, and it depends on a large number of factors: the date of ovulation in any of the cycles may be displaced, the fertilized egg due to various reasons can get to the uterus longer than usually, etc. These and other details can affect the rate of production of HCG. Therefore, the timing is sufficient to a test to determine. Physiological cycle fluctuations can occur absolutely in every woman, even if she has always a clear and regular cycle before.

Modern tests declare the validity of the results of about 99%. But numerous studies show that the false results are significantly higher. The most common reason for this is too early stages of testing. Even a difference of one day plays a big role. Note, that the concentration of HCG, after fixing of the ovum in the uterus doubling every day – increasing very rapidly.

For this reason, doctors recommend testing no sooner than the first day of delay. For greater reliability do a test 2-3 days after the expected start of menstruation. Moreover, whatever the result you get, there is no guarantee that it will be truthful. We recommend you to repeat the test at least once more after 2-3 days.

When to do a pregnancy test, if the cycle is irregular

Doctors recommend doing a pregnancy test at an irregular menstrual cycle, not earlier than 16-17 or more days after unprotected intercourse, using ultra-sensitive tests, or not earlier than 14 days or more after ovulation, taking as a benchmark the longest of all the cycles. The fact is that even with very long or short cycle, periods always occur after approximately two weeks after ovulation – lengthening or shortening of the cycle always takes place due to its first phase.

Women with irregular menstrual cycles should immediately visit a gynecologist if the results of a pregnancy test are positive or even if a second stripe is pale.

So to improve the reliability of the results it is better to do a pregnancy test in the early morning just after waking up. At least, do not urinate for 4 hours or more before the test. With the same purpose,  exclude the admission of diuretics and the use of diuretic products on the eve of the test.

The test for pregnancy after insemination can be carried out only 18 days after the procedure. But the blood for HCG you can check earlier – after 14 days. In the case of an unsuccessful attempt your period starts 12 or more days after insemination.
