Aubrey, not to worry. i had the hardest time keeping weight on me during the first trimester. your appetite should really pick-up by around 18 weeks, and then you won't have any problems gaining weight.

I just had my check up at the doctors and i am 23 weeks and 1 day and i have only gained 8 pounds. however this is my third child. i'm 37 and pretty healthy, not overweight and stay active. my doctor said that all pregnancies are different. i think i am under weight considering my last 2 i gained 51 and 60 pounds. that was 14 years ago. i started out at 140...i hope to only gain 30 by the end of this one.

I started my pregnancy with an average bmi and have been tracking my weight throughout...every time i check it, i'm on the high end of the chart, sometimes even over but even strangers tell me i'm small for how far along i am...this goes to show that no matter what some chart says, every pregnancy is different. as long as mom and baby are healthy, it's not really that important!
