Clots? Tissue?

So my period started on Sunday, was over(ish) by Thursday, but the spotting has continued still. That's not normal for me. 
On top of that, I feel like I have a yeast infection, but I got some monistat and that is clearing up. 
My problem now, though, is that I have clumps of what looks like tissue coming out with the brown spotting that's still coming. I've never had anything like it before and I'm kinda freaked out. Anyone have any ideas what's going on? Next time it happens I'm going to take a picture.
