Normally, menstrual circle is 28 days. Once 28 days, a matured egg is ejaculated from oophoron of women. Egg cells are ejaculated by maturing. The ejaculating of eggs after maturing of egg cells is called ovulation. If the egg cell which is threw to the egg channel with ovulation ( fallop tube) combines with male sexual cells, fertilization occurs. However the improvement will be in womb after fertilization, the womb gets ready for pregnancy. Intra uterine which becomes rich with regard to blood vein gets thicker. If the pregnancy does not occur, this superficial layer which gets thicker is ejaculated with bleeding. This event which is called menstrual bleeding lasts until the ages of 45-49.
