Menstrual cycle: The time between two menstrual cycles counting from the first day is typically 28 days. 365 days divided by 28 = 13, which is one cycle more than there are months in a year. Cycles between 25 days and 32 days are considered normal. Therefore, you may have as many as 15 cycles or as few as 11 cycles per year.
