During pregnancy, progesterone plays an important role in inhibiting the sensitivity of the myometrium (muscle layer of the uterus) to stimuli that promote contractions, thus helping to maintain the pregnancy. Additionally, progesterone also helps to produce thickened cervical mucus, which acts as a barrier preventing bacteria from entering the uterus and harming the developing fetus. Therefore, the correct option is D which includes both of these functions.
