Menstruation

What is Menstruation

Menstruation, or having periods, is part of the female reproductive cycle.

While the average interval between periods is 28 days, many women will have cycles that are either longer or shorter than this.

During a period, the lining of the womb, which is no longer required if a pregnancy has not occurred, is shed and bleeding occurs through the vagina. This bleeding usually lasts between three and seven days.
