ending my 16th week

Hi ladies.I am also ending my 16th week. For the second trimester, I was always hungry and I gained about 10 pounds in the first 3 months but now I have no appetite. I eat a little and I am full. I crave veggies and fruit more than anything else and that seems to be the staple of my diet as of right now. I worry the baby is not getting the right amount of vitamins and wonder where my hunger went. I know that as your uterus grows your stomach gets smaller because of the room the baby takes up but that I am sure is much later on.
