I experienced something similar. Today is one week since I had the medical abortion, and like you, my bleeding and large clots happened the first day, then the bleeding was fine like a heavy flow period for days after. Today I woke up and started off with cramps first, then every time I would put on a pad it would just soak through and mess up my clothes, everything. I started getting scared but I went to the bathroom to have a bowel movement, and since I've been a little constipated, I had to strain. When I did that, I could feel the clots coming and a very very large one passed, and then some smaller ones and I just stayed there for awhile because I wasn't sure what to do.... get dressed, call a doctor, what. Well after awhile it seemed ok, and I showered again and put on clothes. Since then, my bleeding has been back to just like a period maybe a tiny bit heavier. I think maybe in my case, that large clot may have gotten in the way and prevented other stuff from leaving the uterus, and since that passed it allowd my flow to be normal again. I'm no longer concerned. Maybe the same thing could have happened to you? If you're not bleeding any more like that, i wouldn't be too concerned. Just play it by ear and see what happens in teh next day or so. Good luck!
