Menstruation is the body's way of getting rid of the uterine lining every month. The egg is released from the fallopian tube each month. If it is not fertilized then a woman will have her period. If it is fertilized then it will implant itself within the uterus in the lining. This acts as sort of a cushion or protection for the fertilized egg. During pregnancy a hormone called HCG is released. This hormone maintains stability for the growing embryo inside the uterus. Since the woman is pregnant (remember HCG is present), the body knows not to shed the uterine lining. Doing so would extract the growing embryo. The lining within the uterus is what makes it possible to maintain a pregnancy.
