possible hiv symptons

hi everyone, i had unprotected sex 11 and a half weeks ago. i went to get test a week after because i was a bit worried, they said come back in a couple of weeks. i had a couple of white spots on my throat, i went to the doctors and asked him about it he said i have tonsillitis, put me on a weeks antibiotics. this went away, and about a week ago (about 8 weeks after my tonsilitis) a couple of white spots appeared in the same place, i read that this can be a sign of hiv, so i went to get sti tested again and she said id still be in the incubation period. what would be chances i have contracted this virus as im very nervous? this was a one off and the girl said she was clean.
