Answer 2

Answer:

As a woman, your period is your body's way of releasing tissue that it no longer needs. Every month, your body prepares for pregnancy. The lining of your uterus gets thicker as preparation for nurturing a fertilized egg. An egg is released and is ready to be fertilized and settle in the lining of your uterus.
