Period after c section and breastfeeding

Is it too soon for my period to come back? I'm six weeks pp, I'm breastfeeding but also supplementing with formula. I just went to the bathroom and saw bright red blood on the toilet paper. I thought breastfeeding was supposed to delay my period for almost six months?
