I don't know how you ladies gain such little weight. I am 19 weeks with my 2nd boy... started at 128 and am now at 142. lol. I'm not eating crazy like with my first, it's just happening like this. My diet is the same as before I was pregnant. With my first child, I gained about 52lbs total - starting at 126!

I'm 29 weeks and have only gained 9lbs. with my son I gained a total of 15lbs during the whole pregnancy and he ended up being an IUGR baby. I am quite worried that this baby will also have IUGR.

I started out at 131 in August and now at 18 weeks I'm 127 lbs :( I'm eating but not gaining. I am very concerned. I gained weight fast with my first.

I started out at 125lbs pre-pregnancy. Over the first trimester I lost 5lbs just to gain it back early in my second. But unfortunately I've started losing weight again. I dismissed the weight loss in the beginning because I was always sick, but now I'm worried because I eat More than I probably should but yet can't gain.
