Patient's question:
I had sex on the 20th of last month and took emergency contraception the next day. Now my period is four days late. In the morning, I used a pregnancy test and it showed one line, but in the afternoon, it turned into one dark and one faint line. What could be the reason?Doctor's answer:
Generally, pregnancy is tested using a test strip, which should be checked 14 days after intercourse. However, regardless of the self-test results, it is important to consider that self-tests may be inaccurate, and it is best to have a medical check-up. The earliest blood HCG test can be done 10 days after sexual intercourse to confirm pregnancy. You can check at the appropriate time based on the timing of sexual intercourse for more accurate results. If the delay in menstruation is caused by the side effects of birth control pills, as long as you are not pregnant, menstruation will eventually occur. It is still necessary to relax and wait and see.
