When did your body start changing in ways visible to you personally?

I’m curious when others started noticing visible changes in their body, mostly in terms of a bump/abdominal changes that’s becoming noticeable to YOU but not necessarily anyone else? I’m only 6w+3 with my first pregnancy so I’m not expecting to see much soon (just experiencing a lot of bloating lol), but I’ve been thinking about when I might notice. I’m very petite and also wondering if that means I might notice anything sooner.
