If the ultrasound shows thickening of the endometrium and there is incomplete menstruation without heavy bleeding, you can take progesterone capsules, 200mg a day for 10 days, or take dydrogesterone tablets, 1 tablet each in the morning and evening for 10 days. If there is also anemia or infection, you can take blood supplements or antibiotics such as cephalexin to prevent infection. However, if the symptoms do not improve after taking progesterone tablets for more than three cycles or if the ultrasound shows that the endometrium is still thickened, it is better to undergo comprehensive diagnostic scraping or hysteroscopic scraping surgery to clarify the diagnosis and exclude endometrial cancer or endometrial atypical hyperplasia and other lesions.
