Belly shape

Hi, I’ve had two pregnancies before and had normal rounded bump, this one seems high and almost like a ledge, but I’m 22 weeks I know my baby isn’t high above my belly button yet. Is this because I’m still wearing my jeans? They fit and button comfortably but at the end of the day are a little tight, I don’t want to constrict the baby or anything, but the ledge or more “in” part is where my jeans waistband sits. There’s no red mark. tonight I’ve been in leggings for a few hours but it still looks like this. Or is it muscle damage from my last pregnancy?
