Had sex a few days before the period, but after several days, the period still hasn't come.

Patient's question:

No

Doctor's answer:

Hello, environment, mood, certain medications, or illnesses can all cause menstrual disorders. Menstruation arriving one week early or one week late is a normal phenomenon. If your period does not arrive for more than 10 days or longer, it is recommended that you use early pregnancy test paper or check blood HCG for confirmation. If pregnancy is ruled out, consider it as menstrual irregularity and undergo an endocrine examination to identify the cause.
