What is the reason for taking medication for medication the next day and having dirty things flow out?

Patient's question:

No

Doctor's answer:

If there is prolonged bleeding time, bleeding volume greater than normal menstrual flow, or accompanied by significant abdominal pain, it may indicate incomplete miscarriage, poor uterine contraction, or infection, etc. It is important to seek medical attention promptly for examination and treatment. This requires active investigation, as it may lead to inflammation.
