Strep, mono, or herpes???

I don’t know what this is... I’m really scared. I won’t be able to go to the doctors until next week but I’m worried about what this could be.

I recently kissed someone around 4 days ago and have been feeling super tired since, with headaches

Have any of you experienced this :(

It’s in the back of my throat and it feels swollen

I did research and the incubation period for mono is 4-8 weeks so I doubt it’s that since it’s only een 3 days
