Currently, there is no drug or food that can be effective the same day after menstruation. Normal women experience higher progesterone levels after ovulation, and progesterone levels peak 7-8 days after ovulation. If conception does not occur, the estrogen and progesterone drop dramatically around 14 days after ovulation, causing the endometrium to peel off and bleed, resulting in the formation of menstruation. According to the cyclical pattern of change of hormones in the female organism, it can be seen that for women with normal ovarian function and ovulation, there is no drug that can make menstruation earlier. In addition, patients should not blindly take drugs to promote menstruation, if pregnant, the drugs can have an impact on the embryo, and even the occurrence of preeclampsia.
