A woman’s ovulation period is calculated as follows: Ovulation usually occurs about 14 days before the next menstrual period. Ovulation occurs between menstrual periods, and a normal woman’s menstrual cycle usually lasts about 28 days, so ovulation occurs about 14 days before the next menstrual period, which may vary from person to person as the menstrual cycle changes. During ovulation, some changes occur in the woman’s body, the cervical mucus becomes thin and the discharge appears as a clear, pulpy white band with the appearance of egg whites. If there is a need to prepare for pregnancy, sexual intercourse during ovulation has the highest success rate. If there is no need to prepare for pregnancy, it is necessary to take adequate contraceptive measures to prevent unplanned pregnancies as well as miscarriages, which may cause damage to the body.
