I had a miscarriage 11/12/10 (4th pregnancy-I have 3 children). My 2 menstrual cycles since have had more clots and heavier cramps the 1st 2 days-then 1/2 way through my period the bleeding stops for 1-2 days then restarts. So I had an ultrasound 2 days ago and they see endometrial fluid,calcified tissue, and my uterus is enlarged to 6wks still. I did an HCG blood test and it came back negative. My doc says wait another month and we'll do another US to see if it's cleared. I haven't gotten any more info than that and am concerned as to what could be going on. Thanks!
