Has any one else due in July have a problem with weight? My last 2 appointments that's are 2 weeks apart I have been steadily been losing weight. 9 lbs total. My uterus went from 32cm to 35cm in 2 weeks so I know my baby is growing. I have an ultrasound this Monday. I'm just extremely anxious with worry right now. I'm trying to put on weight but I been really nauseous and sick. My doctor assures me that babies will make sure that get everything they need even if I'm not left with much. Anyone have this issue in the third trimester?
