eating

okay, so I was nauseous and throwing up my whole first trimester, around 14 weeks I was able to finally eat and keep food down again. but now I'm struggling with no appetite. some days I can eat a big lunch, but can barely eat dinner. other days I'm really hungry all day. I'm 17 w 2 d and I'm trying to nourish my body for my baby but I'm having a hard time. nothing ever sounds good to eat and I struggle really bad with protein. any suggestions on what to do. I try to snack all day and eat small meals, but by the time dinner rolls around I don't want to eat
