$\underline\bold\blue{Answer:-}$ If the egg is not fertilized or does not implant, the woman's body sheds the egg and the endometrium. This shedding causes the bleeding in a woman's menstrual period. When a fertilized egg does implant, a hormone called human chorionic gonadotropin (hCG) begins to be produced in the uterus.
