If you are treating thickening of the uterine lining, you can usually take progesterone capsules of fifty milligrams each, two capsules in the morning and two capsules in the evening, preferably for ten consecutive days. If you have a normal amount of menstruation while taking progesterone, you can stop taking it at any time. However, if you have not had a normal amount of menstruation for ten days after taking progesterone, you can stop and wait for menstruation, and if you have not had a normal menstruation for seven to ten days, you should go to the hospital for consultation. In addition, if after taking progesterone, after the menstrual period is clean, the ultrasound examination is repeated, and there is still endometrial thickening or polyps, or even menstrual dribbling or heavy bleeding, it may not be suitable for conservative treatment with drugs. It is recommended to do a complete diagnostic scraping or hysteroscopic diagnostic scraping surgery to clarify the pathological results before deciding how to treat.
