I lost weight my first trimester too. Now I'm 31 weeks and I've only gained 15 lbs from my pre-pregnancy weight. As long as the baby is measuring fine I wouldn't worry about it.

I've gained some weight this pregnancy but I'm still not at my pre-pregnancy weight. I gained 100lbs with my son. Some people just don't gain weight. As long as you're child is growing appropriately your doctor should chill out. Think of how many people don't know they're pregnant and never gain a pound. they typically have healthy babies.

I'm the exact same weight I was before. my doc will probably be mad at me on wednesday

I finally got back to my pre-pregnancy weight. My doctor wants me to gain another 5-7 lbs in 5 weeks.
