This is my first pregnancy, and I'm curious when did everyone feel their baby move for the first time?

I am 13 weeks and 3 days, and I am just curious when everyone felt the flutters and their baby move for the first time?? I am a little heavier set so I am convinced I won't feel it for a while but today after eating my lunch I was having this crazy feelings like a flutter? but then I thought maybe it's all in my head at this point?
