Week 3 recovery

Hi ladies,

I had our 2nd little one 3 weeks ago by an emergency c section.

I felt great week 2 and was taking walks and moving around...but Now week 3 the incision hurts again and lots of “twinges” and just feeling like I want to sit down a lot. Also feels like the skin is pulling. Is this normal? I have surgical glue on my incision but I don’t think I’m supposed to take it off myself?
