the last couple days my baby has been moving and kicking the crap outta me! I haven't really felt anything until now,it's really exciting! not trying to be gross but it feels like I have gas trapped in there when he is moving right now! it's uncomfortable!! idk if it's him or it's really gas! this is my first and I'm 23 weeks... any feedback?
