Touchy subject..

I've recently had an abortion. Well 5days ago, the first day I had lot of blood clots and all that, then it all calmed down to just weird blood, but I've just got up to get ready for work, and I've passed a blood clot about the size of a bobble (I can't think of anything else) it was more oval shaped, I'm worried if that should be happening 5 days after the tablets, can anyone help me? Please, and before anyone asks, I had my reasons, God only knows I would of loved to of kept.
