Growing fast?

Dorthea
Has anyone else notice that they've gotten bigger faster with her second pregnancy? I found out I was pregnant at four weeks and now at 7 1/2 weeks I can't even wear my pants I have to wear a belly band. I just find it kind of strange that I'm already showing a bit. I haven't had my first appointment is next week so I don't know if there's more than one in there yet. LOL but I was curious if anybody else has had that happen, their belly growing faster than it did with the first one?
