If it wasn't for my boobs getting a heap bigger and my nipples feeling like they have razor blades hanging out of them then I don't think I would feel pregnant at all.
My pants are a touch tighter but other than that it doesn't feel real at all, I actually feel rather detatched from it all at the moment. I can't wait to have a definate belly. I as thinking just lastnight that it doesn't seem real at the moment. MAybe it will when we start to tell people?
