What is a typical menstrual period like?

During your period, the thickened uterine lining and extra blood are shed through the vaginal canal. Your period may not be the same every month and it may not be the same as other women's periods. Periods can be light, moderate, or heavy, and the length of the period also varies. While most periods last from three to five days, anywhere from two to seven days is normal. For the first few years after menstruation begins, longer cycles are common. A woman's cycle tends to shorten and become more regular with age. Most of the time, periods will be in the range of 21 to 45 days apart.
