Gas or baby?

I get consistent "kicks" I've been told it's probably gas,  but gas happens in your stomach, not all over your abdomen. I know about the whole imaginary pregnancy when you desire to be pregnant so bad but I don't want a baby and I swear I actually feel these "kicks" I've taken pregnancy tests, even though I still get my period and it still comes out negative. I'm a bigger girl so I know if I was pregnant it wouldn't show. I've been extra bloated and the top of my stomach is harder than it usually is. I don't actually think I'm pregnant but it's the only thing I can think why I'm feeling these "kicks". I assumed at first the were phantom kicks but I've never been pregnant before so? Could I have some ovary syndrome or something? Does anyone know anything similar?
