Generally speaking, a woman&39;s menstrual cycle is 28 days, so if she does not ovulate during her menstrual cycle, she will not get pregnant in theory. However, sometimes the menstrual cycle is not necessarily regular, that is, it is not necessarily 28 days. If an egg is released from the ovary during the menstrual cycle, and if no contraceptive measures are used during sexual intercourse, there is a chance of pregnancy.
