Hello ,I'm from myanmar I used protection but unfortunately condom did outburst my penis exposed for like 10 seconds inside her Vagina then changed new condom and completed sex (sex duration was total 20 minutes ) exposure event on July 14 .I also received oral sex from her using condom that's why condom outburst because of less lube on going action , i think though . she was actually a sex worker ,she denied to go HIV test of my requested and she never had any medical records regarding HIV as well . so i decided to put myself on PEP as Tenvir-EM (TDF/FTC) seeing with a doctor in this case 21 hours of event after .On September day 2nd (6 weeks after exposure I tested non-reactive on HIV , VDRL test as well . On Sep day 15th (8 weeks after exposure , 4 weeks beyond the PEP ) i made Hiv 1 &2 antibody test again result outcome as non-reactive .Have you ever seen 4 weeks after PEP negative later turn into positive ?
