The menstrual period, or menses, is the shedding of the uterine lining which flows from the uterus through the cervix and exists through the vagina. The average menstrual period lasts 3-5 days and happens monthly, however menstrual periods can vary greatly from woman to woman. The flow of blood can be light or heavy, and the cycle length (the time between the first day of menstruation and the day before the next period begins) can also vary significantly. Your regular menstrual cycles usually mean that you ovulate regularly, while irregular menstrual cycles are often related to hormonal problems such as ovulation problems.
