Food advice..

Im 10 weeks, and im having a hard time eating. I will be completely starving, but then when i sit down to eat i feel sick, and can only eat a very small amount. Nothing sounds good to eat, nothing even looks good. I eat what i can, but its not enough and i feel weak.. im not sure what to try or do.. any advice for a first time mom-to-be?

UPDATE***

I bought some lipton cup-o-soup, and i can eat it!! Doesnt make me sick and tastes amazing. Going back for my second bowl now :)
