I'm starving!

Br

I am 5.5 weeks. I've barely gotten through these last couple days. I am usually always hungry and always eating, occasionally I'll wake up with a growling stomach. But these past few days, I have been getting so hungry it's making me nauseous. And now I have a loss of appetite, I can't seem to get anything down. I haven't had morning sickness yet. It's just so hard to eat, but I want to so bad. I am scared for baby and myself. Is there anything I can do? I can't stand not eating or being hungry, little snacks just don't suffice. I would have to literally eat non-stop...any suggestions or knowledge of when this might end?
