Eating help!

I need some help. I’m currently 6 weeks pregnant with my first and I’m starving! All the time one hungry. I’ll eat and a half an hour to an hour later I’m starving again. I know that in the first trimester they tell you not to gain a lot of weight and I’m really trying to be healthy but I’m always hungry and can’t find something to calm my stomach. I eat healthy snacks and drink a ton of water but nothing seems to curb my appetite. Please any advice will help!
