What are the reasons for menstruation after three months of giving birth and then stopping?

Patient's question:

I had my period three months after giving birth, which lasted for a week, but this month it hasn't come. The test result shows I'm not pregnant. Could you please tell me what could be the reason? Is there any problem? I'm very worried

Doctor's answer:

Hello, regarding these symptoms, I consider it might be caused by menstrual disorders. It is recommended to maintain a positive and cheerful mood, avoid cold drinks, and consider using Chinese herbal medicine Danggui Hongzao Granules to treat menstrual irregularities. Also, focus on improving nutrition, get more rest, and wear soft, cotton underwear.
