Bleeding question (TMI, sorry)..update

I had my son 7 weeks ago, the bleeding from after the birth stopped on monday. On Wednesday, it started again only REALLY heavy and bright red. I was thinking maybe its AF, however I'm EFB, so it would be "strange" to get it so soon. However, I'm forced to change pads every 3-4 hours because they are saturated. The bleeding is not like my normal periods. Since this is my first child I don't know if this is somethng I should be concerned about, or could it just be my period and its different because of the birth.
I don't know if this matters but I had a c-section. If anyone has any advice I'd greatly appreciate it.

ETA: I went to the doctor and they have me going for bloodwork and have to monitor me. They may have to give me a hormone to the stop the bleeding.

My doc said I could bleed on and off for 8 weeks after having my son. I bled for five and then had a week off and AF came. However I never bled as much as your describing. I would call your doc.
