[Hormone] Progesterone [Produced By] Ovaries [Function] 
Prepares the womb for pregnancy and sustains pregnancy. Where estrogen is dominant in the first half of the menstrual cycle, progesterone takes over in the second half. Side effects of progesterone are a bloated stomach due to water retention, cravings for sweet things and tiredness. The synthetic (man-made) version of progesterone (used in some contraceptive pills) is called progestin.
