Hello, I would be happy to help you with your question.
It is possible that you did not have complete evacuation of the uterus
with the D&C. Your body is behaving like there is still some tissue in the uterus. Most women have very rapid cessation of bleeding and cramping in the 1-2 days after a D&C. You need to get checked out as soon as possible and request an ultrasound
to assess the uterus.
I hope that this helps and good luck!!
