If bleeding occurs two days after menstruation, progesterone or a hemostatic drug such as Yunnan Baiyao can be used to stop the bleeding, but it is important to find a clearer cause before applying the drug. For unmarried women who are not sexually active, it is safer to understand the condition of the endometrium through ultrasonography before applying the appropriate medication. For women who have already had sex, it is safer to perform ultrasonography and, if necessary, hysteroscopy to understand the condition of the endometrium and then apply the above mentioned drugs according to the specific pathological results. Therefore, the application of medication is not the first priority for the above-mentioned cases, but the main thing is to find the cause of the disease.
