Three days after the crowd, you had sex. On the 13th day, there was a small amount of bleeding. What should I do?

Patient's question:

Sure, I can help with that. Please provide the content you want to be translated.

Doctor's answer:

The cervical erosion you described, cervical inflammation, is generally caused by childbirth trauma, improper sexual activity, or retrograde infection of vaginitis. Currently, treatment can be done using microwave therapy or herbal medicine for clearing heat and promoting diuresis.
