29 weeks and feeling really off

I’m 29 wks with my second, and since yesterday I’ve been having a lot of pressure and pain and general uncomfortableness and pain along the area of my previous c section (Jan 2020). It’s especially worse when my bladder feels full, or when I’m walking or moving or trying to bend over. I have had a hard time eating because everything is making me feel nauseous the last two days, and when I am sitting the pressure is also making me very nauseous feeling.

Has anyone with a previous and recent c section experienced this with a following pregnancy? I’m not sure if this is Normal or if I should be a bit concerned around the pain where the incision was.

Thoughts??
