I believe many female friends will promptly undergo a pregnancy test after unprotected sex to check if they have the possibility of getting pregnant. Usually, we use a pregnancy test stick for testing. So, do female friends know the reason for detecting parallel bars in 7 days of sexual intercourse and 10 days of parallel bars? Let's follow the editor to learn more.
What's going on with 7-day parallel bars and 10 day parallel bars in the same room
Using early pregnancy test strips to detect early pregnancy is prone to errors and may not be very accurate. If pregnancy is detected, it is best to have a blood test for HCG to make a more accurate judgment. The use of early pregnancy test strips usually requires more than two weeks of sexual intercourse. Therefore, detecting a horizontal bar within 7 days may be a false detection, and more accurate methods should be used for detection.
How long after sexual intercourse can pregnancy be detected
In fact, under normal circumstances, if women pay attention, they can usually determine whether they are pregnant about 18 days after sexual intercourse or 7-10 days after menstrual delay.
Because after sperm and egg combine to form a fertilized egg, it takes 6-8 days for the endometrium to implant, and then 7-10 days for the HCG secreted by the placenta to enter the urine. The working principle of pregnancy test strips is to detect the HCG value, which is the value of human chorionic gonadotropin. This hormone is produced by the placenta and usually appears in the urine a few days after pregnancy. However, due to its small amount, it is difficult to detect at the beginning and becomes increasingly apparent only after 10-14 days.
I believe that after reading this article, all female friends will have a clear understanding of what 7-day parallel bars and 10 day parallel bars are all about, and they won't be so surprised next time. After sexual intercourse, it is not immediately possible to detect pregnancy. We still need to wait for a period of time, so female friends do not need to be too anxious.
