Stretchy tummy feeling?

I am 6wks pregnant and am getting these uncomfortable stretching feelings around my tum. It is a combination of the feeling you get after doing sit ups with the feeling you get after eating too much. I am definately not eating much at the moment so it isn't that. It is a lot of the time and I don't know if it is just things moving around in there or something to be concerned with. I feel silly talking about pregnancy symptoms as it is so early.

Is anyone else experiencing this?

Thanks xxx
