First postpartum period

Kelc
I had my son 9 weeks ago and I just started my first PP period that landed me in the ER. I was going through 7 pads In an hour and bleeding through my clothing as well. The nurses in the ER told me that my bloodwork came back normal, and that I should just keep an eye on it. This is not normal bleeding. I'm pissed... 
Any one else have bleeding like this??
