This is my first pregnancy, I'm 8.5 weeks, and I'm worried about the fact that I keep losing weight... I know it's not crucial to really gain in the first trimester, but thanks to nausea and a lack of appetite I can't even maintain. I started this pregnancy at 125 and now I'm down to 118. At my ultrasound last week the doctor said my baby was measuring a little big so I guess I shouldn't be too worried? I just don't want to affect my baby by not being able to maintain enough weight.
