would it be possible at all?

I felt very small movements at 14 weeks. Just really light flutters. I am not sure about 12 weeks.

Nope. 

If you feel anything, it's gas.

I'm not sure. I felt movement at 14 weeks this time around, it's only been a year since my last pregnancy though. My other two were both at 17 weeks.

probably not i didnt feel movement with my 2nd till i was about 14-15 weeks...and your due on my birthday!!!!  

I felt Jayden move first at just before 16 weeks  

I highly doubt it. It's probably gas. ( I had A LOT of that around 12 weeks! haha)

okay, i just wanted to prepare my self to know what it was when i felt any movements if so, any or none at all at 12 weeks. So i guess i have two weeks to go. But then, that might not be the case, because we are all different.

Yes I'm sure it's possible, but not very likely.
I started feeling movements around 13/14 weeks and it was my first (and only) pregnancy.

No... 

I remember being anxious for those first flutters...you'll know it when you feel it but for now...it's too early!

First pregnancy (longer term... ) no.
But any after, yes. I felt my second BORN early..... My first born was late. 3 pregnancies in between that and I never felt anything though.

Quoting Mrs.Brittany Due*5-23-201:“ would it be possible at all?”

I felt flutters at 13 weeks. They were doing an ultrasound and I hadn't looked at the screen when I felt something move. I said something about it and they showing me that she was moving all over the place. They were chasing her around the entire time during that one. And all the following ones too.

Quoting Cartman:“ Yes I'm sure it's possible, but not very likely. I started feeling movements around 13/14 weeks and it was my first (and only) pregnancy.”

what did it feel like?

If you do feel anything it would probably be gas or maybe the feeling of having gas at least.

Yes. It is.
I felt Patton for the first time around 12 or 13 weeks. Nobody believed me until I said "i think i can feel him moving" to my doc during a u/s (i wasn't looking at the screen at that moment because he'd JUST started it and I was talking to someone else in the room) and yup, he was moving.
