Appetite problem🤮

Hi my dear ladies..i am on my first trimester, week 7. I had trouble eating at first but my appetite has improved now. Only one problem, i will eat half way and then suddenly no appetite for that food, i stop immediately. It happens to all the foods and drinks that i take. Eat/drink halfway and then suddenly appetite got cut off and i crave for other things. It's making me very hungry and i'm worried about my baby's health😭
