*going to call doctor tomorrow when they open if I’m still feeling this way but wanted some reassurance until then*

I’m 5 weeks post partum Friday from my 3rd c section. This was my best one and I was up within 5 hours after and have been basically pain free since end of the first week. The last few days above and around my incision started to become sore again and now I think it’s a little red. I’ve felt extremely tired today but I have a newborn. No fever or any other else. Is it even possible to get an infection at this point? No part of my incision is open
