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.

I'm at 12 weeks, I started at 120 and LOST 5 pounds this week. I eat fine. So, I dunno what's going on or if it's normal.

I started at 130lbs, 5'4. I am now up to 141lbs at 19 weeks, and I've been 141 since 16 weeks. As long as you are eating healthfully and indulging in small cravings, you will be fine.

I'm underweight so mine says I need to gain a few pounds the first trimester which I have already gained 3. Says I need to gain 28-40 pounds during my pregnancy. Wowzers.
