You don’t gain any weight during pregnancy? Does that mean there’s something wrong with baby? I’m 16 weeks and I’ve gained 0 lbs. I eat like there’s no tomorrow. I also don’t have morning sickness. Because of my insurance, I’ll have my FIRST ultrasound at 20 weeks. Cant help but wonder. My first pregnancy I gained 60 lbs. lost it all after birth and this pregnancy I haven’t gained anything. I currently weigh 150lbs. Not overweight and was told not to gain more than 35 lbs.
