The painless person said that after half a month, the ultrasound showed that there were still blood clots that had not been expelled, which was an induced abortion.

Patient's question:

No

Doctor's answer:

You should have a D&C procedure now, because blood clots can also cause prolonged bleeding. If it's not done cleanly and blood clots are found later, a D&C will be necessary. Prolonged bleeding can lead to adhesions and endometrial implantation (growing into the uterine muscle layer), which would make the procedure more difficult and cause greater damage to the uterus. The blood isn't expelling outside because the uterus isn't contracting well.
