The correct option is A Progesterone
Women commonly take progesterone to help start menstrual periods that unexpectedly stopped, treat abnormal uterine bleeding associated with hormonal imbalance, and treat severe symptoms of premenstrual syndrome (PMS). Progesterone is also used in combination with the hormone estrogen to "oppose estrogen" as part of hormone replacement therapy. If estrogen is given without progesterone, estrogen increases the risk of uterine cancer.
