Question

uterine linigs begin to break down and bleeding result

Answer 1

Answer:

Abnormal uterine bleeding is bleeding between monthly periods, prolonged bleeding or an extremely heavy period. This can be caused by hormone changes, cancer, fibroids, polyps or early pregnancy.

Answer 2

Answer:

When the follicular phase begins, levels of estrogen and progesterone are low. As a result, the top layers of the thickened lining of the uterus (endometrium) break down and are shed, and menstrual bleeding occurs.
