This is my second c section and it’s much different recovering this time than the first. It’s taking longer. I’m 3weeks 3 days pp and also had a tubal removal. I’ve already been to the doctors because of redness with my incision and doctor said it didn’t look like anything to worry about.

1. I feel like my incision has a smell to it. No puss that I can see. Has anyone else had this and does that mean an infection?

2. What is the best pp shape wear to help with stretched skin and also good for the c section scar and the pressure needed to apply to it to help with irritation?
