Please help😅

So I’m 6 weeks and 4 days pregnant. I haven’t really had any nausea yet but if I don’t eat for what feels like every two hours I get really shakey, lightheaded, and I feel like I’m gonna pass out. Has anyone dealt with this in early pregnancy? It doesn’t matter if I eat a big meal or not I’m always STARVING in the next hour or two and I don’t wanna over eat and have unnecessary weight gain.😕 please give me some advice❤️

(Ps I added a picture of my cat because I feel like posts with pictures get more attention🥲)
