Anyone else find that the top of their stomach has really firmed up but not the bottom?

I'm a plus size mama, so I know it'll take me a little longer to actually show. But I feel like from pretty early on only the top of my stomach has been the only thing to change. I can feel him sitting really low, but the bottom of my stomach has not changed AT ALL! It's really starting to bum me out 😔

Is the top of my stomach being hard just everything moving around to make room? And if so, why is he not rounding me out more?!

This is me at 15 weeks:

This is me at 20 weeks (this morning):

I wanna show this kid off! But no one knows I'm pregnant 😭 because I don't look like it!
