It is normal to take progesterone for menstruation, which is mainly influenced by the secretion of estrogen in the body. If it is the right time to get your period, sometimes even if you are taking progesterone, it will not affect your period. Progesterone is mainly used for the treatment of irregular menstruation, and it is usually necessary to stop taking it after 5 days, and the withdrawal bleeding will occur around 3-7 days after stopping the medication, and the menstruation will start. If you experience menstruation while taking the medication, you need to stop taking the medication in time. Taking progesterone itself is to encourage the opening of the uterus and stimulate the uterus to menstruate. If you are taking progesterone for irregular periods, you need to go to the gynecology department of the hospital within 3-7 days after your period clears to have an ultrasound examination of the uterus to see the thickness of the endometrium. If the endometrium is still thick, you need to cooperate with the doctor to do scraping treatment, which will help to restore normal menstruation.
