The best time to test for pregnancy with a pregnancy test is about two weeks after having sex. Some women who have fertilized eggs early can test about ten days after intercourse. However, because of this early time period, some women have a short time for the fertilized egg to be laid in their bodies, so they are prone to false negative symptoms. In order to be more accurate, it is recommended to take an early pregnancy test about 14 days after sexual intercourse. In addition, when using a pregnancy test, it is recommended to use the first urine in the early morning, because the urine is more concentrated at this time, so the content of human chorionic gonadotropin is higher, and the test result will be more accurate. Of course, if a pregnancy test shows two bars, it is advisable for women to go to the hospital to have a blood HCG test to confirm it, because the blood test is the most accurate.
