How do high levels of estrogen and progesterone during the luteal phase of menstrual cycle affect the uterus?

Luteal Stage: This is the stage that leads to the next period.  It lasts for about 12 to 14 days. The follicle that released the egg will very quickly become what is known as the "Yellow Body" (in Latin  it's name is "Corpus Luteum").  This produces an high level of progesterone (and a small amount of estrogen) which is required to generate the mucus on the uterus surface to assist a fertilised egg
