उत्तर
The menstrual cycle is the cyclic change of the reproductive tract of a primate female. This period is marked by a characteristic event repeated almost every month (28 days with minor variation) in the form of a menstrual flow (i.e., shedding of the endometrium of the uterus with bleeding). Only during pregnancy does it temporarily cease.
