How much bleeding after 4wk mc?

Breanna • 2 angels with tiny wings up there watching over me.
I'm so confused. I think I may have miscarried yesterday bc of what was in the toilet, it wasn't much but it didn't look right. I bled for about 22 hours before hand, but it wasn't heavy, thick, or deep red in color. I have spotted twice prior to this but not for as long and not with the end result looking the way it did. They were tiny pieces of.. tissue it looked like? Which is why I think I may have miscarried. But I don't/didn't have hardly any cramping at all, and although I've continued to spot lightly, nothing else has happened. I am going to the doctor tomorrow, but I just can't shake this. Also, I've been taking Progesterone since Wednesday, and the bleeding began Friday. Does anyone have any similar experiences, or any at all that could help me understand what could be happening?
