VIH infection, I am very scared!!

Please help me to know what is the possibility to be infected in a risky situation like this: A prostitute, who I am sure is VIH+ because in the place she works they drink alcohol and they have unprotected anal and vaginal sex with many people.
I was so stupid!!, I was so drunk at that time, she gave me unprotected oral sex for three minutes I did not ejaculate in her mouth, this situation was 8 weeks ago. I have had some symptoms of VIH primoinfection like diarrhea, headache, swollen lymphs. two days ago I noticed that I have bleeding gums, I never had this before, including swollen lymphs. is bleeding gums a symptom of VIH infection?

I have read on the internet that people who is VIH+ have many oral problems so I think she has them. So I very scared. Additionally I notice a day after the risk a wound on the prepuce caused by her teeth during the oral. I am very scared please help me thank you.
