Patient's question:
HelloWhen is it least likely to get pregnant during a month?
Doctor's answer:
Hello, taking a 28-day menstrual cycle as an example, the period from 3 to 5 days after the first menstrual period is called the "menstrual period," and after it ends, the first safe period begins. The two safe periods between menstrual cycles are separated by the ovulation period. Ovulation almost certainly occurs on the 14th day before the next menstrual period, or 5 days earlier and 4 days later. This is also known as the "dangerous period." Since male sperm can survive in a woman's body for 3 days, it is necessary to move the dangerous period forward by 3 days from the aforementioned 5 days before the 14th day to account for any unexpected events. This day marks the end of the first safe period. The second safe period begins 4 days after the aforementioned 14th day and ends on the day of the second menstrual period. It is clear that the second safe period is safer than the first. Usually, ovulation occurs 12 to 22 days after menstruation, entering the dangerous period.
