I am 13w 4d and don't have much of a tummy to show yet. I can see it a bit when I am naked and I also notice that my belly button is not as deep as it used to be. I love clothes that hug my body tightly, and you could see just a bit of that tiny tummy today, but that is probably because I know. It is still pretty small and I don't think anybody noticed. When did you start showing with your first? On one hand I want a tummy to show off and be proud of, on the other hand, I don't want a big one because I have a weak back and am very small framed, so it will probably be very physically demanding on me to have a big one.
