Patient's question:
Doctor, hello: I had my period on the 10th of last month, and we had sex on the 8th of this month. Is that day considered a safe period? Also, would I get pregnant if I don't use contraception during the safe period? How is the safe period calculated?Doctor's answer:
The day of ovulation is approximately 14 days before the first day of the next menstrual period. The five days before ovulation and the four days after it constitute the fertile window, as sperm can survive in the body for 1 to 3 days, and the egg, once released on the day of ovulation, survives for 1 to 2 days. Therefore, this period is defined as the fertile window, which is the time when pregnancy is most likely to occur. For example, if the menstrual cycle is 28 days long, the day of ovulation would be around the 15th day after the start of menstruation, and the fertile window would be from the 10th to the 19th day after the start of menstruation. It is easier to conceive the closer you are to the day of ovulation.
