How long after sex can I use a pregnancy test?

How long after sex can you take a pregnancy test? You can take a pregnancy test 8-11 days after sex. The hCG value can be measured by blood test 8-11 days after conception. Blood hCG appears earlier than urine hCG, and blood hCG test is much more accurate.

The working principle of using early pregnancy test strips to test early pregnancy is to detect the hCG value, that is, the value of human chorionic gonadotropin. This hormone is produced by the placenta and generally appears in the urine a few days after pregnancy, but due to the small amount, it is not easy to test it at the beginning, and it will become increasingly obvious after 10-14 days.

It should be noted that although many pregnancy test tools indicate that women can do pregnancy self-tests one day after missing their normal menstrual period, in fact, not all pregnant women release hCG hormones at the same speed and in the same amount. This varies from person to person. Doing a urine test too early may result in a negative reaction.

How long does it take for the early pregnancy test paper to be able to test pregnancy

The working principle of using early pregnancy test paper for self-testing pregnancy is to detect the hCG value, that is, the value of human chorionic gonadotropin. This hormone is produced by the placenta and begins to be secreted 10-14 days after conception. After secretion, it will first appear in the blood and then in the urine through the circulatory system. However, due to the small amount, it is not easy to test it at the beginning. It will become increasingly obvious until 1-2.5 weeks of pregnancy. The effect will not be good if it is too early or too late.

At least 10 days after intercourse, choose morning urine for self-testing. The concentration of hCG in morning urine is higher. It takes several days for sperm and egg to combine into fertilized egg, implant in the uterus, and form an embryo. hCG will not appear in the blood until a few days after pregnancy, and because of the small amount, it may not be detected at the beginning.

Generally speaking, you can use an early pregnancy test strip 7 days after your menstrual cycle is delayed or 10 to 14 days after having sex, or as early as 33 days after your menstrual period stops. If the early pregnancy test does not show whether you are pregnant, you can do another test about 37 days after your menstrual period stops.
