Detailed explanation-1: -If the egg does not become fertilized, the lining of the uterus (endometrium) is shed during menstruation. The average menstrual cycle lasts 28 days. The cycle starts with the first day of one period and ends with the first day of the next period. The average woman ovulates on day 14.
Detailed explanation-2: -Having a lack of periods (amenorrhea): Missing one or more periods without being pregnant could be a sign of anovulation. Having a lack of cervical mucus: Right before and during ovulation, you usually have the most vaginal discharge called cervical mucus. It usually looks like raw egg whites.
Detailed explanation-3: -The egg travels down the fallopian tubes. If pregnancy doesn’t occur, the egg is reabsorbed into the body. Levels of oestrogen and progesterone fall, and the womb lining comes away and leaves the body as a period (the menstrual flow). The time from the release of an egg to the start of a period is around 10 to 16 days.
