Onset of menstruation: Dydrogesterone is a kind of progestin, after taking this kind of drug, due to the hormone effect, there may be endometrial shedding manifested as vaginal bleeding, suggesting that there is a case of menstruation. 2. Cervical lesions: When bleeding occurs after taking the drug, it is necessary to rule out the existence of cervical lesions or endometrial lesions that cause bleeding, and ultrasonography and gynecological physical examination are needed to determine this. 3. Problems with miscarriage: vaginal bleeding during the administration of dextroprogesterone in pregnant women indicates that the birth control is unsuccessful, and gynecological ultrasonography is needed to determine the expulsion of the gestational sac. Therefore, if you experience increased bleeding after taking Deferiprone, it is recommended that you consult the Obstetrics and Gynecology Department of a regular hospital to determine the specific cause of the problem.
