This study is currently closed to enrollment.
Cervical mucus is the fluid at the opening to the uterus, or womb. During a normal menstrual cycle, cervical mucus changes in response to two natural hormones that the ovaries make: estrogen and progesterone. Many birth control methods that women use prevent pregnancy by thickening this mucus, making it less likely for sperm to enter the uterus. Our goal is to better understand the effects estrogen and progesterone have on the cervical mucus in your body.
