What do i have??????????

well last night around 3:00 am i throw up.....and this whole day i've been in bed and ate at the table.....and on the computer just now. The only thing I ate today is one of those lunchable nachos that was in my fridge and a coffee. i haven't thrown that up yet but if i get up and walk around i feel like i have to throw up....just sitting here makes me want to throw up... i don't have swine flu right? just worried
