Is it safe during the days before menstruation?

Patient's question:

No

Doctor's answer:

The safe period is divided into the pre-ovulation safe period and the post-ovulation safe period. The period from the day after menstruation ends to the day before the start of the ovulation period is the pre-ovulation safe period. The period from the day after ovulation ends to the day before the next menstrual period is the post-ovulation safe period. Generally speaking, the post-ovulation safe period is safer than the pre-ovulation safe period.
