It has been three days since my period, and the test strip showed no pregnancy. Is it reliable?

Patient's question:

No

Doctor's answer:

Generally, you can use a pregnancy test 10 days after sexual intercourse to check if you are pregnant. In your case, if you had sexual intercourse more than 10 days ago, you can take a pregnancy test. If the test result is negative, it does not rule out the possibility of delayed menstruation due to high stress. It is recommended to maintain a calm mood and continue to observe for about a week.
