I weighed 125 at he beginning of my first pregnancy I lost weight before I gained anything due to morning sickness and by the end I only gained 36 pounds. Don't worry once your farther along it will start catching up but like said above as long as your eating the way you should there is nothing to worry about
My weight was about 131 and now it's about 135-136
Well if you dont mind me asking how much did you weigh before? But you should feel lucky as long as youre eating as much as you should then youre fine a lot of women dont gain much weight until later in their pregnancies
