The bleeding part of the menstrual cycle is the uterus's natural mechanism for sloughing off a "wall" of tissue that had prepared itself to make a fertilized egg a comfy place to embed itself. The lining itself is mucoid, with blood vessels, and its' the mucous and blood that passes during menstruation.

P.S.There is a phenomenon called Menstrual Synchrony that occurs when women live together or in groups...even best, or very close friends. It means these women's cycles are in synchronicity...ovulation occurs at the same time, as does menstruation. My daughter and her three closest friends had babies all within about 2 weeks of each other...twice. It was quite interesting.
