What is the overall purpose of the muenstral cycle?

The menstrual cycle is the series of changes a woman's body goes through to prepare for a pregnancy. About once a month, the uterus grows a new lining (endometrium) to get ready for a fertilized egg . When there is no fertilized egg to start a pregnancy, the uterus sheds its lining
