C section stomach recovery

I am having my second c section . My first was 5 years ago so I don't remember exactly my recovery. Just a few questions for anyone who recently had a c section or remembers lol.
How long after you left hospital was stomach still really bloated?
Did you use a stomach binder ?
Did you get a belly flap over your incision and did it go away? ( I didn't with my first)
I see a lot of women say they lost all the weight and was still left with a belly flap. I have searched online up and down for why some women experience a belly flap and some women don't . Does it have anything to do with the doctor performing the c section like how they cut you or where or is it just how your own body heals? Just looking for insight on it .
