You had protected sex and the protection did not fail during sex, therefore your risk never existed. Since you were never exposed to the risk, your test will always come Negative. Your tests are conclusively telling that you do not have HIV. Further testing is not needed, because it is waste of time and money.
Nobody had ever reported Positive after receiving his/her negative test at 6 weeks, even when done older 3rd generation antibody test. You are no exception, so rest assured, your name will not appear in the Guinness Book of World Records, :)
Suggest you to stay away from HIV related net searching and move on with your life. You do not have HIV
Way over tested. But I get it. Anxiety will do that. I’ve been in your shoes.
But you DO NOT have HIV and your tests have proved that.
Maybe consider working with your doctor for anxiety and whatever else may be causing you issue.
