I've gained 25 lbs at 32 weeks. It sounds like a lot, but its all in my belly and boobs, my legs/face/butt look the same. I just keep trying to eat healthy, and praying for a healthy baby. If I end up with a belly when this is over I'll worry about it then.
That said, I do feel huge. This belly hurts to carry around and it gets in the way lol.
