I took the plan B pill and now I feel like death

I am on birth control but I was only on day 4 of my pack.  I went and bought magnums because my boyfriend is very well endowed, we put the condom on and it fit and everything (I say this because I feel like it's the reason the condom broke) and we had sex. I stand up and realize the condom had broke, his cum was dripping down my thighs. No biggy just go to the store and buy the pill. 

I feel like hell. I have a headache that's making me feel drunk, I'm nauseas as hell, I can't eat and I'm shaking and so dizzy I can't see straight. I feel like I am on drugs, this is ridiculous. I also have a fever is any of that normal at all??? Like I'm BURNING up and I'm sitting infront of my ice cold AC sweating.
