I am definitely in that "I just feel fat and not pregnant stage." If look at my bare belly I think I have started to pop. But when I have clothes on, especially when I'm sitting, I definitely feel fat. It is so strange to feel all the changes that come along with this expanding belly. The other day I got in the car and was trying to figure out why my seatbelt felt so weird and it was because it was touching my belly in a way it never had before. Exciting and weird.
I am totally jealous that people who are fewer weeks pregnant than me can already feel their baby. In my more neurotic moments it makes me worry, but the bigger belly and the still sore boobs make me feel better. I am eagerly waiting for the flutters to start.
I think the best part of being pregnant so far is not having my period any more. Love it!
