Any other FTMs starting to look bigger?

I'm 13w and just started noticing in the last few days that my tummy below my belly button has had a small but very firm and defined roundness instead of being flat.

Could it just be bloat? It doesn't look or feel like any bloat I've ever experienced. And I know for a fact that it's not constipation haha.

For context I'm 5'4", 113lbs, 24in waist, and borderline short/average torso length. I think it's super obvious from the side when I'm wearing anything fitted. Wondering when it'll be obvious to others!
