So Last Night I Ate A Peanut Butter And Jelly

So last night I ate a peanut butter and jelly sandwich and the roof of my mouth swelled up, it hurt really bad and I eat them all the time, then this morning I ate a bagel with cream cheese and the same thing happened. And now I just ate a hamburger and the same thing happened. I've never been allergic to anything and nothing like this has ever happened to me, what's going on?
