recently I just had sex with a hooker. We had protected sex and i perform cunninglus to her. During cunning, I dont have any mouth ulcer but i use a mouthwash before it The first 3 weeks is normal after that. Then at week 4 I had a flu and cough. Then at week 5 my lymph node under my jaw is swollen. Just want to know if this is hiv or other. I kind of freaking out right now. So help me guys
