I am feeling the same. I couldn't wait until the 12wk scan to make sure that there was a bubby in there and now I am 16wks and 3days and I absolutely can't wait until the 20wk scan so I can check that bubs is doing fine. I have had little flutters here and there and not every day so I wouldn't worry as they have so much room to move around in. A friend and I think that we should have a window in our tummy so we can check to see how bubs is doing. LOL
