Postpartum bleeding tmi

I will be 6 weeks pp Tuesday and the past two weeks I have had dark pp blood and then I stopped bleeding and then this week I have been spotting bright red blood and all of a sudden I am bleeding heavily bright red blood. Everytime I move it gushes sorry tmi I use the very thick overnight pads and the are soaked in two hours. I am cramping also. Could this be my period? Could I hemorrage this late pp? Just trying to see if anyone else is bleeding like this pp
