Is this strep throat or pharyngitis?

Is this strep throat or pharyngitis? I quit smoking but smoked about 4 last week with a friend out in the cold and I didn’t have a jacket. I also kissed someone who was coughing the day before (stupid I know). I ended up feeling sick on Saturday with a headache, a little nausea and a temp of 99. What do you think it could be? Helppp.
