Is it too early to feel?

Stesha
I'm 11 weeks and this is my second baby....at night it feels like I have hiccups in my belly ...only at night if I try to lay on my left side, and I'll keep feeling them until I turn over...I know that you feel things earlier the 2nd time around but everything I read is telling me it's gas, and it's too early...baby? Or gas? Opinions please....
