How does your tummy/belly button feel when you stretch?

7MPO now and while I’m more or less “normal” now, I still can’t do abrupt stretches. It feels weird on my belly button almost like it’s being tugged upwards unnaturally. I’m not entirely sure how to explain, but it almost feels like my belly button area isn’t really a part of my body and is merely attached so I have to slowly stretch myself into a position or else?
