The chances of conception are less when you are not ovulating than when you are ovulating, but you cannot rule out the possibility that you will get pregnant. Most women get pregnant during ovulation, which is 14 days before the next menstrual period, and the five days before and after ovulation are considered the fertile period. The chances of pregnancy are higher if you have sex during this period. Women’s ovulation time is affected by a variety of external environment, ovulation may occur in advance or after the wrong, or sudden ovulation and cause pregnancy, so not ovulation will also have the chance of pregnancy. If you are having normal sex and have delayed menstruation, you need to consult your doctor and have the relevant tests performed to determine if you are pregnant.
