What is the reason for a little blood after taking medication for 21 days?

Patient's question:

No

Doctor's answer:

Hello! The vaginal bleeding after a miscarriage usually lasts for 3-5 days, and it does not exceed 15 days in the longest case. Advice: If the bleeding duration is too long, the amount of bleeding is greater than the normal menstrual flow, or accompanied by significant abdominal pain, it should be considered as a miscarriage.
