##HELLO FRIEND##
##HERE'S YOUR ANSWER##

The endometrium changes throughout the menstrual cycle in response to hormones. During the first part of the cycle, the hormone estrogen is made by the ovaries. Estrogen causes the lining to grow and thicken to prepare the uterus for pregnancy. Once the lining is completely shed, a new menstrual cycle begins.
