Something's wrong with my stomach

Hey there... so, here's the deal:
I’ve noticed something lately that's starting to bug me... When I blow all the air out of my lungs—like, a super deep exhale until my stomach is totally flat—and then start breathing back in slowly, things look a little wonky...
One side stays pretty flat while the other side kind of bulges out... Or maybe it's the other way around, I can't quite tell. It’s not like a massive ten-inch gap or anything, but there’s definitely a visible difference of maybe an inch or two. It seems to happen right around my belly button or just a bit lower down.
My first thought was maybe a hernia, but I don't know if that makes sense. There isn't any actual lump popping out, and it doesn't hurt at all—not even when I'm lifting stuff or if I cough. When my stomach is just relaxed and normal, everything looks perfectly fine. The only thing is, could this be a hernia just starting to develop?🤷
It just feels so weird.
If anyone has any ideas, please let me know. Honestly, I'm starting to get a little bit worked up about it.

No need to freak out—it’s perfectly normal. No one has a perfectly symmetrical stomach because our guts aren't built that way. Plus, everything changes based on what you eat and how your digestion is acting.

Asymmetry is especially obvious when you're looking down at your own midsection from 😁

A hernia would look totally different—usually, that shows up as a distinct, bulging little balloon sticking out.

Thanks a million, sweetie! 😁
You totally calmed me down 😉
