If a period lasts for twenty days, a large amount of estrogen can be taken orally or a curettage can be performed to stop the bleeding, or oral Chinese medicine can be taken to regulate it. Normal menstruation is around three to seven days, but menstrual bleeding for twenty days is definitely abnormal and can easily lead to anemia and reproductive tract infection. If you need to stop bleeding quickly, you can choose to take oral medications containing estrogen such as Tegretol and Eucerin, which can repair the lining quickly and stop bleeding within two to three days. Diagnostic scraping is also feasible for married women to reduce the thickness of the endometrium to give hemostasis and perform pathological examination at the same time, but postoperative antibiotics should be used to prevent infection. If the above two modalities are unacceptable, oral administration of proprietary Chinese medicines such as Kun Ning Granules and Female Gold Tablets is recommended to adjust ovarian function and restore normal menstrual pattern. However, proprietary Chinese medicines are slower to take effect and are suitable for women without complications who do not need to stop bleeding immediately, and the course of treatment is longer, taking two weeks or even longer.
