In fact the lining of the uterus known as the endometrium undergoes changes in response to hormone levels during the cycle.
In the first half of the cycle known as the follicular phase the developing follicles secretes increasing amounts of estrogen hormone which encourages regeneration of the endometrium after ovulation. There are important changes in the endometrium aimed at making it suitable to receive a fertilized egg these changes are brought about by a secretion of progesterone from the corpus luteum.
