Weight Gain

Ch
Anyone else not gained any weight over their pre-pregnancy weight in the 7th month or further. 
Doctor says baby is fine and actually measuring larger but Mom (Me) I'm actually 1 lb less than when I started got down 6lbs earlier on (No nausea no vommiting) got up to 2lbs over pre-pregnancy weight, and now I'm 1lb less. I guess I'm all baby. What's your story ?
