What is the reason for having intercourse during ovulation and then experiencing a three-day delay in menstruation?

Patient's question:

No

Doctor's answer:

This situation is possible to be pregnant, but the chance is relatively small. Generally speaking, it is normal for a woman's menstrual period to be one week earlier or later. It is recommended that you wait a few days to see, and if necessary, you can use a pregnancy test kit one week after the menstrual period to confirm whether you are pregnant or not.
