Is it strep throat or allergies?

[cocoakiiirby]

I have had a sore throat for the past few days, on and off. I don't have a fever, and don't feel sick or more tired than usual at all. My dad checked my throat, and he said it looked normal. I DO have dust mite allergies, and I am sleeping in a not-so-clean room, so I am thinking maybe post-nasal drip is the culprit.

But what do you guys think? Could I have strep with no fever and not having any feeling of sickness?
