Healthy/filling snacks!

DS
I'm 11 weeks and I cannot  stop being hungry. I eat pretty healthy already and I'm determined not to gain a lot of extra weight this pregnancy but I am so hungry all the time! I don't want to eat heavy things cause they are usually high carb and not as healthy. So I'm curious what any kind of carb free, light, healthy, filling snacks would've found? (Doesn't really have to be carb free but I'm not opposed to that :) ) I snack on a lot of fruit veggies and cheese but i feel like I just can't keep myself full anymore.
