First baby movements?

I'm going to be 14 weeks tomorrow. I am 5'5 and 112lbs. Very slender. Last sunday, 13 weeks; I felt my baby move. It wasn't like what everyone says it feels like though. It was a poping sensation. like popcorn poping. It was low in my abdomen. It was not gas, I know that feeling because I have gas constantly in my pregnancy. Plus my tummy usually hurts with gas, or I will have bubbles in my stomach. This feeling was no where near that. I haven't felt the poping sensation again since then. Is that normal? Like it's almost been a week and I haven't felt anything again. Are the movements that you can feel really that far apart in early pregnancy?
Yes this is my first pregnancy.
