the CURRENT guideline for a CONCLUSIVE test result is 3 months. those that you read about who are testing out to a year or more, are doing so because of their inability to accept the FACTS regarding testing. (most of them have ocd or are hypochondriacs)
if you have a 12 week negative test result...you do NOT have hiv...period...no ifs, ands, or buts about it.
accept your status and move on with your life.
always use condoms for penetrative sex until you know the status of your partner. sex lasts a few minutes...HIV LASTS A LIFETIME.
Good that you are seeking some help with your HIV anxiety, nobody tests positive after 12 weeks, most test positive earlier in fact.
