I'll be 19 weeks tomorrow and I can't say I don't have a belly because I do. But it hasn't really "popped" yet. When I have no shirt on, you can tell I have a belly but when I do have a shirt you can't really tell. I just look chubby unless my shirt is tight. I can't wait until my belly looks round and I actually look pregnant. I know eventually I'm gonna look like that but just curious when it'll happen. When did everyone "pop" with their first pregnancy?
