Hungry but not?

Rachel • Married to the most wonderful man and father. We have a beautiful 1 year old girl and currently in our second pregnancy
I'm 6w pregnant and hit the point where I've lost my appetite. I don't have any morning sickness but I just have no desire to eat. But of course my brain is telling me to eat at the same time. Should I just eat something? Or wait until I get hungry enough. I don't really remember how I felt with this durning my first pregnancy because by the time I figured out I was pregnant I was almost in my second trimester and my appetite had come back
