This is my first pregnancy and I started out at 104 lbs. I'm 30 weeks and am now at 136 lbs. I thought you were supposed to gain 25-35 lbs throughout the entire pregnancy? I feel like such a cow! I try to eat pretty healthy with the junk food I crave thrown in every once in a while, and I walk everyday. The weight just keeps coming though :( is this okay? At this rate I'll probably gain nearly 50 lbs at least! I thought that since I was petite to start out with I wouldn't gain this much :(
