Menstruation is cyclical uterine bleeding that occurs approximately once a month in mature women and is discharged from the body through the vagina. The hormones secreted by the body cause the endometrium to undergo cyclical changes in preparation for the development of the fetus. If pregnancy does not occur, the endometrium will shed and bleed, resulting in menstruation, which will be discharged from the body through the cervix and vagina.

Normal menstruation varies greatly from person to person. The regulation of menstruation is controlled by hormones from the ovaries and the pituitary gland. The menstrual cycle is calculated from the first day of menstruation and lasts about 28 days. But the length of the cycle varies from person to person, and is not always fixed. It is normal for menstruation to be advanced or delayed within 7 days. Menstruation usually lasts 3-7 days, with an average of 5 days.
