no appetite at all!

I am now 11weeks pregnant and I don't have any appetite at all. I have lost 3kgs for the past few weeks because I don't eat normally. I just eat about 3 spoons of rice and that's it! I force myself to eat fruits and veggies as much as I can but I don't think it's enough. I am worried for my baby's nutritional state. All I can seem to tolerate is biscuits since it doesn't make me want to vomit. Is there any way to improve my appetite?
