Should I be worried?!! (Warning: gross picture)

Tiffany

I’m 5 weeks pp and have been bleeding like crazy. It slowed down about 2 weeks ago then came back with bright red bleeding.. my OB says that it’s my period but I don’t think it should be lasting 15 days and still be bright red. Now I’m passing large clots. So my question is: should I be worried about the size of this clot and the length of my first “period”?
