Here is the English translation of the provided text, with the return characters kept as they are: "Menstruation came on and left by the afternoon. A few days later, it came again."

Patient's question:

No

Doctor's answer:

Consider it may be menstrual irregularity. It is recommended that you go to the hospital for an ultrasound examination to understand the condition of the endometrium and ovaries. If they are normal, you can take traditional Chinese medicine orally for regulation. If it is ineffective after 2 months of regulation, you should have your sex hormones checked to rule out endocrine disorders causing menstrual irregularity, and then regulate it accordingly.
