Should I call my doctor?

I stopped bleeding from delivery at 5 weeks pp and all of a sudden at 7 weeks pp I started bleeding bright red again, that was nine days ago and it seems to be getting heavier and heavier.

I originally thought it was either more bleeding from delivery or my period (I’m not breastfeeding) but it’s been well over a week now with bright red bleeding. I saw a post this morning about pp hemorrhage so now I’m wondering if that’s a possibility? I know I was at risk for hemorrhaging right after delivery, I’m not sure if that would increase my chances of a late pp hemorrhage.
