two days ago i had unprotected sex with my boyfriend, twice (it wasnt our first time doing it but we lost our virginity with each other some months ago); first time he pulled out and came in my mouth a bit after. he didnt urinate after this and some hours later we did it again: he pulled out, a bit later he came in my mouth. i swallowed both times. the same day, he bit me on the right side of my neck way too hard (near my right tonsil). the day after (yesterday) i was feeling really hot and i thought i had fever but didnt check it until evening. also, at night my head was hurting really bad, my right tonsil was really swollen but my throat didnt hurt and i had 38ºC of fever. i took some painkillers and slept. today, i still feel the same; my right tonsil is really swollen and i can feel the saliva passing on my throat and it feels bad (doesnt hurt, stings, i cant describe it very well), my head hurts from time to time (has gotten better since i took some painkillers), my neck which also hurt yesterday (forgot to mention that) is better too but the fever only gets down when i take the painkillers. what do i have? ive heard that fever can be a sign of pregnancy, but aint it a bit too early for that? ive had sex on the 13th, 16th, 20th and 21st of june, for some reason showing these symptoms since yesterday (21st). ive also heard that swollen tonsils, sore throat, headaches, fever (etc) are some of the symptoms of HIV; is it possible for me to be infected? as i said, i lost my virginity with my boyfriend, never had any kind of sexual activity with anyone else and it's the same with him. what can i possibly have?
