Thanks for your query.
You could be having the bleeding and clotting due to imcomplete surgical termination.
This is a known complication of a surgical abortion
However, I wonder why it was considered normal, because the way you describe it, you should not be having pools of blood 3 weeks after a termination.
I suggest you see a gynecologist as soon as you can.
Please have an internal check up and a transvaginal ultrasound
, which will tell you if tissue and blood clots
are still inside the uterus.
You might require blood transfusion
, and a repeat evacuation if the need arises.
