pregnant or not

So I'll start back to when I have been feeling sick. Me and my boyfriend went to outback steak house and that next day I got sick thought maybe I had food poisoning the next day I ate some asparagus and got sick that night as well threw up nothing but asparagus so every morning I get dizzy and nauseous and at night some days I get sick. Last night we ate mcdonalds with family and I got sick that night went to bed woke up and still felt sick. Our sex life is pretty active right now but I'm on the pill and we still use condoms just in case I've missed my pills for 4 days and had to take a double dose but because of that we haven't been sexually active. What are your thoughts on this.
