Actually, no appetite during the first trimester is normal. Be sure you do eat some healthy food, but most importantly, take your prenatal vitamin. During the early stages of pregnancy, your baby is not growing so much as developing, and not having an appetite is actually a survival mechanism. It would help women to avoid eating harmful or potentially toxic foods at this very vulnerable period of their baby's development. But, there are some important vitamis and minerals whose deficiency can be equally harmful, that's why you want to take the prenatal vitamin. When you do have an appetite, choose foods that make a healthy nutritional contribution to your diet.
Once you get into the second trimester, most likely your appetite will return.
Congrats on the pregnancy!!
