After 7 days of cohabitation, if your period comes on time, will you not get pregnant?

Patient's question:

Please ask: Urgent inquiry
My girlfriend and I had sex seven days before her period, and she got her period next month. Is it possible that she might be pregnant!!??!!!!!!!!!
Other: None

Doctor's answer:

This possibility is very small. Around the time of menstruation, it should be the safe period, meaning there is no ovulation, and the chance of pregnancy is unlikely. Since menstruation has already occurred here, it should not lead to pregnancy. If you are still not sure, you can use a pregnancy test kit to check.
