thank you for using healthcare magic,
chances of HIV
infection is only there if your partner was affected.. if possible try to find out her HIV status..
but from history i dont think you have any risk.. 8 to 12 weeks are enough to develop antibody and if you were infected then test would have been positive.. but its not so relax..
you can go for other test like p24 antigen ,pcr , viral load
for your satisfaction.. its ok if you got done from reliable private lab..
