How long does a normal menstrual cycle last
A menstrual cycle is the period of time from day one of your menstrual period to day one of your next period. Menstrual cycles may occur at the same time each month or be irregular. Typically, a cycle occurs about once a month, but can be as short as 21 days or as long as 35 days and still be considered normal. Menstrual flow lasts about 3 to 7 days.
