Umm...I'm already at 38 pounds and the time before last when I was at the dr, she told me I would be gaining around a pound a week. I've been gaining a bit more than that, but I've also heard that your weight gain slows towards the end.
I started gaining pretty early, and I've got quite the bump. My body is really starting to hurt though, and I don't know how much more I can handle! I might increase my swimming just to give my body a break.
