Nauseous and can't eat?

Alyssa
App says I'm 5w3d(not sure if it's correct or not). I've been nauseous almost constantly for the past two days. At first I was hungry what felt like every hour, but now just the thought of food makes me feel like I'm going to vomit. 
Is this normal? I feel like something may be wrong because I'm having to force myself to eat. And I've found that slim jims are the only thing I can eat without feeling like I'm going to vomit.
