Hi Bea
I agree, your bubs is well cushioned in there and some people don't feel movement for a few weeks yet, don't stress, your bubba will be fine!
I hear ya on the "blimp" thing. I have no idea how much weight I've put on so far, it wouldn't be all that much but when you're used to being a certain weight and then all of a sudden you have all this other weight, well you do start to feel like a blimp, so I guess it's just all part of the fun
