Hungry!!

I'm 7 weeks tomorrow. I eat breakfast, lunch and dinner snacks occasionally, but I'm trying not to "over eat" I guess you could say because I'll get sick but I just ate 2 corn dogs.. And drinking water but I feel like I haven't ate ANYTHING ALL DAY!!! I don't want to keep over eating and make myself sick.. But I also hate the thought that I NEED to eat something hair to make my stomach stop growling. Help?
