A lot of times you're actually losing excess weight you don't need and the baby and everything is making up for it.
I tend to loose weight n not gain during my pregnancies this is my third and I'm loosing weight once again but doctor isn't concerned at all
I'm in the same boat. My baby is 2lns and I have actually lost 12 lbs this pregnancy. My Dr said baby is "living off the land" so to speak. They are taking everything they need from you and you just aren't adding any extra. Its perfectly fine as long as your Dr isn't concerned.
