Progesterone is in charge for the female regulation of menstruation and ovulation period. And progesterone can be induced to stimulate menstrual periods in women if there is a decrease of progesterone or to control overgrowth in uterus lining for women who are on the estrogen hormone replacement therapy. In women progesterone levels are relatively low during the preovulatory phase of the period higher after ovulation and elevated during the luteal phase.
Progesterone levels tend to be < 2 ng/ml prior to ovulation and > 5 ng/ml after ovulation. With pregnant women, progesterone levels are initially maintained at luteal levels. The luteal-placental shift in progesterone support of the pregnancy and levels start to increase further and may reach 100-200 ng/ml. If the decrease in progesterone levels is critical and labor is on the way it may be species-specific because after placenta delivery and during lactation progesterone levels are very low.
Progesterone has other purposes but it is dangerous to use without consulting the doctor especially if the woman is pregnant because it can damage the baby. Such medications may have peanut oil and peanut allergy do not go well with progesterone due to a possibility to risk of having a breast cancer, stroke, blood clots, heart attack etc.
