Progesterone tablets are commonly used for dydrogesterone and progesterone, which are progestins whose main role is to protect the fetus and regulate the menstrual cycle. If a person has irregular menstruation, progesterone tablets can be taken orally for 10-12 days during the second half of the menstrual cycle, and menstruation will come when withdrawal bleeding occurs after stopping the medication, if the menstruation is regulated by applying a minimum of three cycles. If used for fetal preservation, it can be used in case of preterm miscarriage, or if there is a history of miscarriage. This medication has no effect on the fetus and does not increase the incidence of fetal malformations, so it can be used safely.
