Answer:

• The menstrual cycle is the regular natural change that occurs in the female reproductive system that makes pregnancy possible. The cycle is required for the production of oocytes, and for the preparation of the uterus for pregnancy. The menstrual cycle occurs due to the rise and fall of estrogen.
• The menstrual cycle provides important body chemicals, called hormones, to keep you healthy.
• If pregnancy doesn't happen, your body doesn't need the thick lining in your uterus. Your lining breaks down, and the blood, nutrients, and tissue flow out of your body through your vagina. ... If you do get pregnant, your body needs the lining — that's why your period stops during pregnancy.
