Please help. I'm a 22 year old heterosexual female. In September I had unprotected oral and vaginal sex with ejaculation. Now before I go any further I do not know if my one night stand partner is hiv positive. I don't know much of his history but he does drugs and is very promiscuous. Before this encounter I know I was completely clean. I had 4 negative hiv test in 6 months before this. Anyway. We had sex September 18th and I done a rapid hiv finger prick at 23 days. It was negative. So I really didn't have any symptoms I just have anxiety now. 6 months later I have a huge swollen lymph node and a little oral thrush. And I'm terrified I can't sleep I Google all day. What were my chances of getting hiv from this one time encounter? I feel like I'm going to die everyday from the crippling anxiety and OCD I need help anything is appreciated
