Post partum bleeding

Emmi
Hey ladies what's going on with me? Bled pretty consistently for about 2 weeks post partum then it tapered off (like with spotting brown blood) and then acted like it stopped, but then came back with bright blood again. Then it has gone thru that same cycle for a 2nd time where it tapers off and now red blood again. Is this normal to go back and forth like this? Or should I call my docs?  I'm almost 4 weeks post partum and getting about done with this lol. My daughter is adorable tho and worth everything when I look at her :)
