If my experience and that of my friends means anything, for your third baby you could start showing before you even take a pregnancy test! Every woman carries differently. I always started showing early , but am very toned when I'm not pregnant. But then, a friend of mine who is more heavy set didn't look pregnant until she was in her last trimester. You will most probably notice changes to your body sooner this time than with previous pregnancies since your uterus is 'used to' stretching, and will strectch out sooner making you 'show' sooner. I have quite a few friends with 3 or more kids and one thing they all agree on is that the more kids you have, the sooner you show.
