Loss of appetite

Kayla
So I'm 17 weeks and I'm just not hungry like usual. I'll eat my main meals- breakfast, lunch, dinner but that's about it. They are really small meals too. For example- cereal, half inch chicken sub, and corn with a few pieces of steak.. (What I had yesterday lol) is that enough?? I guess I expected that I would want to eat more .. My scale actually went down rather than up and I never had any morning sickness.. Is this normal? Anyone else in this boat?
