Patient's question:
Here is the English translation of the provided text, with the return characters kept as they are:"It's just that a few days before my period, it's yellowish-brown and there are blood clots. How should a 23-year-old woman regulate her menstrual cycle?"
Doctor's answer:
Hello, after taking emergency contraception pills, the majority will experience withdrawal bleeding again within about a week. This is a side effect of the medication. Taking emergency contraception pills may also lead to menstrual disorders. In your case, the withdrawal bleeding you are experiencing is likely due to taking the pill. If the bleeding lasts too long, you can take hemostatic medication to address the symptoms. There are many methods for treating diseases, but since each patient's condition is different, the treatment approach must be tailored accordingly. Therefore, it is necessary for patients to seek professional medical evaluation as soon as possible for detailed testing so that the appropriate treatment can be administered.
