Gave head and now a sore throat?

On Saturday night I had sex with a guy I like. He didn’t finish inside me, instead I finished him off with oral. But now my throat hurts and I’m not sure if it’s because of a cold, irritation from deep throating or something else. The back of my throat looks slightly irritated, but also it has been freezing where I am and it’s been Halloween weekends so no one is dressing appropriately - and it has been raining nonstop here. All grounds for me to get sick in addition to me being very stressed currently. There are no white spots on my throat, just slight redness and feels scratchy to swallow.

What do you guys think?? (I currently cannot go to the doctors to get tested/checked)
