Hello,
The duration of bleeding from a miscarriage is different for every woman, but the bleeding should stop within about two weeks in most cases. You should however get a routine pelvic examination and ultrasound uterus done to check for any retained products of conception.
It is very difficult to precisely confirm a diagnosis without examination and investigations and the answer is based on the medical information provided. For exact diagnosis, you are requested to consult your doctor. I sincerely hope that helps. Take care.
Do they know you have not stopped bleeding? Sometimes you can have retained fragments and may need D&C. I wish you the best but let them know.
