Coud I be pregnant or is it plan b?

on June 16 I had anal sex with my bf but wen he came in my butt and some of it came out and got near my vagina. I cleaned my self quick and the following day about 26 hours after intercourse I took plan b. I took plan b next choice took one pill and the second pill two hours after taking the first one. I had no symptoms after taking plan b and now just yesterday,10 days after taking plan b, I felt like I was going to vomit and I felt dizzy. And im having a milky odorless discharge and I havent gotten my period ever since i took plan b. Is it possible I'm starting to get symptom of plan b 10 days after taking it or can I be pregnant? Please help !
