Hello. I believe I had raw sex with a given positive individual and some 5 days later I got tested but the result was negative. But I didn't have any idea the person had hiv then. But now I have reasons to believe so and i'm so scared. I was supposed to be on prep but on that day I didn't take the prep pills as I should have or maybe I did. I just can't recall correctly. I would have gone to a healthcare facility but I can't right now. I'm very scared. And also, I have a sore of some sorts on the roof of my mouth, it appeared like 3 days ago as a bump after I ate something hard. But now it's just like bruises and i'm having difficulty eating. Is that a symptom of hiv?
