Hello bigdogdog.

I think there is no "right" or "wrong" there. No one can tell you exactly how many days after exposure to HIV your immune system would have created enough antibodies to be detected by the test. That varies from one individual to another. We are talking about probabilities here. At 8th week after contact I think most people would have createad the antibodies, but doctors, on a safe attitude to minimize false negative tests (test result negative despite HIV infection), advise waiting 3 months. Others may advise 6 months, to minimize even further the risk of a false negative. At 6 months this risk is so low, that for practical purposes one can consider itself safe.

Take care to notice that the risk of a false negative can never be zero (lab mistakes, unusual immune system behaviour,...), but it can be as low as to make it unrational to be affraid of being given a false negative. After a 3 month-negative or 6 month-negative, if you still feel anxious you should probably seek a thereapist to help you with that.

I would try to relax if I were you. I read your story on the other post and, adding to the fact that you had only one occasional risk episode, the fact that you are testing negative at 8 weeks, you are probably not infected. Do the test at 12 weeks and get reassured. Do the test at 6 months and get further reassured. But try to work on your excessive fear, on my opinion one can never be too safe or imprudent, but one should also not be obssessively scared on low-probability situations, as yours it is right now.

Think positive, I hope these informations ease your mind.
