You can usually test for pregnancy with an early pregnancy test about a week after you missed your period or about 15 days after intercourse. If a woman is sexually active, she can choose to receive an early pregnancy test about 15 days after intercourse, and if the result is positive, it means there is a possibility that she is pregnant. However, women need to go to a regular hospital to receive a blood HCG (human chorionic gonadotropin) test to confirm pregnancy. In addition, if a woman wants to know whether she is pregnant in advance, she can also choose to go to a regular hospital to receive a blood HCG test about 10 days after intercourse, which is considered to be the gold standard for pregnancy tests. During pregnancy, you should follow the doctor’s instructions to have a checkup on time, and if you feel unwell, you must go to the hospital in time and follow the doctor’s instructions to deal with the treatment.
