Under normal circumstances, a period will occur about 7 days after stopping progesterone, but this cannot be generalized. Progesterone is a progesterone drug that can cause the level of progesterone in the body to rise, which can cause a sudden drop in the level of progesterone in the body after stopping the drug and can cause the endometrial lining to shed bleeding and form a menstruation. If the thickness of the endometrium is normal, you will usually have a normal period about 7 days after stopping the medication after applying progesterone. If the endometrium is thin, estrogen should be added to promote the growth of the endometrium, and when it grows to normal thickness, progesterone can be added to make the endometrium shed. If you have a menstrual period after medication, you should pay attention to cleanliness and hygiene to avoid inflammation or pathogenic infections during the period. At the same time, it is necessary to ensure regular work and rest, balanced diet and keep warm.
