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:

Besides the 4 days before and 5 days after ovulation and the menstrual period, the rest of the time is called the safe period, during which pregnancy is generally unlikely.
The method for calculating ovulation is as follows: If the menstrual cycle is regular, the first day of the next menstrual period is counted as day 1, and then 14 days are added, or 14 days are subtracted from the total cycle length to determine the ovulation day. The ovulation day, along with the 5 days before and 4 days after it, together constitute the ovulation period, also known as the risky period.
