usually after exposure and entry of the virus into a persons body, some persons may be affected by " Acute retro viral Syndrome" after 2 to 6 weeks. The most common symptoms will be fever
, Swelling of lymph
nodes in your neck/groin etc, rash
.The proportion of persons developing these symptoms will be more in persons who will become seropositive for HIV..but they can occur in patients who may not become HIV positive also.
But all these are not very sensitive/specific to HIV. Confirmation by a serological test is the best way to confirm. HIV antibodies
may take 30 days to 6 months time to develop ( Window period), so you will not be sure of your negativity at least till after 6 months of your exposure. So best thing for you to do is to go for p 24 antigen assay or nucleotide amplification tests, which can detect the virus as soon as 2 weeks after the exposure.
Hope your test results will come negative..and try to be cautious next time
