Post partum bleeding vs period?

I had my daughter via c section June 13, bled for about 3.5 weeks then it went away. Had sex July 10th, and 12th and started bleeding again, bright red. It's been going on for about 3 days now. Decent amount but not heavy (not soaking a pad an hour) does this sound like post partum bleeding still or period? I've been exclusively pumping since I was in the hospital if that info helps
