Do I have strep or a regular sore throat?

2 days ago I started feeling just a little bit of pain in my throat, so I started taking airborne. Yesterday my sore throat got a lot worse and it would hurt a lot when I would swallow. Yesterday I also had a very bad headache, dizziness, stuffy nose, and mucus. Today my sore throat got worse, but all I have now is the sore throat and a stuffy nose and a little bit of mucus. (no more headache and dizziness) I keep taking airborne, Alka-seltzer, and cepacol lozenges, but the pain doesn't relieve. I don't have a thermometer, but I don't think i have a fever (maybe a mild one).
