Wow, I'm in the second trimester group now!
I am 14 weeks and just starting to show I think. I am 5'11 and had a bit of a pot before that I could suck in but now its very hard to do!! I can feel the bump when I lie down so its definitely on the way.
Silly me didn;t weigh myself at the start so I have no idea how much weight I've put on, but I'm just going to run with it.
