I had an exposure on 2/4/17 with csw with unknown status. I had protected vaginal sex but a scratch cut due to itch on my penis shaft are making me worried it might not covered by condom and maybe had contact with vaginal fluid. Also had oral sex giving and receiving without protection.
On 5 week after exposure i had antibody finger prick test and it was negative
On 8 week i had Ag/Ab Screening (CMIA) and it was non reactive.
1. Is my exposure high risk to contract hiv?
2. About my test, do i need to do a retest on 12week?
