Hi everyone please help me with my anxiety i was dating someone and was sexually involved with her for about 20 days we had sex around 8-10 times but it was protected sex with condom and only kissing was involved and she also gave me a blowjob couple of times later on i found out in 2014 she was in a relation with a guy who was born with HIV and she admitted they even had unprotected sex quite often but she said she did not get it and i asked her to get tested recently in 2021 september she went for a test called HIV 1+ 2Ab+HIV P24 AG and the results were non reactive and no evidence of hiv infection. My question is how is it possible that she did not get HIV given the fact she had unprotected sex with A hiv positive person in 2014 and is her recent test in september accurate? Is there any reason for me to be worried or should i let it go? Thanks any help is appreciated..
