I Felt The Baby Move!

So I'm sitting here at work and all of a sudden I feel something! It's in my lower right pelvic area. Not a kick of course but it feels like the baby rolled around or something! A lot of you ladies have been feeling something down there so I googled and I found something that said you can feel a flutter as early as 10-12 weeks and you can feel kicks as early as 16-18 weeks and DH (or anyone) can feel kicks from the outside as early as 18 weeks and on. So I KNOW this wasn't gas because I've had gas a lot in the last couple of weeks and if feels like a rumble, this thing I felt just now feels like a roll over! lol. Hard to explain but amazing!!!
