On the 20th of last month, we shared a room. This month, my period is delayed and hasn't arrived yet, it's the 4th day. On the 6th.

Patient's question:

No.

Doctor's answer:

Hello! If you haven't used contraception during sexual activity, there is a possibility of pregnancy. After a 7-day delay in your menstrual cycle, you can use a pregnancy test kit to check. If two red lines appear on the test paper, it indicates a positive result, meaning you are pregnant. Additionally, 10 days after sexual activity, you can visit the hospital for a blood HCG test, which is the most accurate method for checking pregnancy.
