If your period has exceeded 10 days, you have had sexual intercourse in the past, and you have not used contraception, it is recommended that you collect morning urine for an early pregnancy test to rule out the possibility of pregnancy. If you are not pregnant, it is likely to be caused by endocrine disorders, it is recommended that you can promote menstruation, for example, you can drink a bowl of hot brown sugar and ginger water every day for 3 days to promote the effect of menstruation. If you still do not have menstruation, it is recommended that you can take oral progesterone pills to promote menstruation, once a day, once 2 pills, take 3 days, 3-7 days after stopping the drug will come to menstruation. Progesterone pills have a side effect that dizziness is likely to occur after taking the pills, so it is recommended to take the pills orally before going to bed, so as to avoid the occurrence of dizziness. If you still do not have your period on the 8th day after stopping the pills, it is recommended to go to the hospital for a checkup to rule out premature ovarian failure as the cause of menopause.
