TMI question!!

So I am 3 months postpartum and I keep having terrible abdominal cramping and I have diarrhea with it. It’s so painful. Tonight I was experiencing severe cramping. The cramping is right where my uterus is. I can’t tell if it is coming from my uterus or bowels... When I finished going to the bathroom this was in my discharge. I had a C-Section so sometimes I just worry if I’m getting the cramping from that. Does this look normal? I’ve never experienced this. My last period was 2 weeks ago and I’m not supposed to get it until 2 weeks from now
