I had a friend who was on clomid and estrogen (clomid helped her get pregnant, but thinned her lining, so the estrogen helped counter that), then she went on progesterone as soon as she got a bfp.
and found this on healthywomen . org
"During the reproductive years, the pituitary gland in the brain generates hormones that cause a new egg to be released from its follicle each month. As the follicle develops, it produces estrogen, which causes the lining of the uterus to thicken.
Progesterone production increases after ovulation in the middle of a woman's cycle to prepare the lining to receive and nourish a fertilized egg so it can develop into a fetus. If fertilization does not occur, estrogen and progesterone levels drop sharply, the lining of the uterus breaks down and menstruation occurs."
