I'm 30 weeks and lost 10 pounds in the beginning and have only gained 3 of the pounds ds back but I'm definitely bigger and it's all good as long as you are getting bigger and the baby is growing the pounds don't matter
I'm 37 weeks n have only gained the 10 I lost in the beginning ..n that's all baby n placenta n fluids. As long as your eating good n babies gaining on track and your doctors are not worried I wouldn't worry too much.
