Which days after menstruation are less likely to get pregnant

Patient's question:

Which days after menstruation are less likely to get pregnant

Doctor's answer:

Except for the 4 days before and 5 days after ovulation and during the menstrual period, the rest of the time is called the safe period, during which pregnancy is generally unlikely.
The method for calculating ovulation: If the menstrual cycle is regular, ovulation can be calculated by starting from the first day of the next menstrual period and counting 14 days, or subtracting 14 days from the first day of the next period to determine the ovulation day. The ovulation day, along with the 5 days before and 4 days after, together constitute the ovulation period, also known as the dangerous period.
