Since I was already overweight when I got pregnantmy doctor wanted me to lose more to make sure iI didn't get diabetes while pregnant. I barely eat and I just started gaining weight back idk how
I was excersizing and got down to 230lbs. I was 2 months when I found out so I had been losing weight too. I've been maintaining my weight. Fluctuating between 230-235lbs. I've had morning sickness since I was 6weeks so I know that curbs my appetite quite a bit. But like the dr says if the baby's is healthy and on track, you shouldn't worry.
I know several plus size pregnant women who lost significant weight during their pregnancies. As long as your baby is fine and your doctor isn't concerned, I would try not to worry about it too much. The most important thing is to try to get nutritious foods down and fluids down whenever possible.
