Hey, I went to a prostitute in a really sketched out area in Vietnam. She offered me a handjob and we did mammary intercourse(penis between breasts). All of these action with lubricant on my penis and between her breasts. There was no kind of anal, vaginal or oral sex. I did not see her vagina as she told me strictly no intercourse or kissing. The next day i got a fever and i took antibiotics and it went away. I was extremely nervous so i asked her about her status and her english wasnt that good and couldnt understand me. I then waited 32 days to get tested with something called CMIA ag/ab test. Thankfully it was negative, I had a sore throat after that and the doctor told me to take another and if it came negative not to worry. I tested at 48 days which again thankfully was negative. I was really happy untill i started having swollen lymph nodes on my neck which are extremely painful and have been there for a month now.
1) Because my swollen lymph nodes came after the test would have that affected it? Is it a false negative?
2) Are my tests reliable/conclusive?
3) How high is my risk?
Thank you for your help, much appreciated.
