i'll leave it alone after this but i'd like to know what the accuracy of this test and what the testing window would be for this test. thanks again.
Protected sex is always zero risk, so you are negative and your test was a waste of time. It is not surprising that you got a sore throat nor that it went away because billions of other negative people experience that too. You are safe and can move on to a happy life.
You should definitely believe it, because you didn't have ANY risk for HIV to begin with. Protected sex keeps you safe from HIV as long as the condom didn't visibly rip - and you would 100% notice if it had. There's no such thing as tiny holes that can cause HIV transmission. It really is just that simple.
ANY test you take will be conclusive, and negative. Despite the symptoms you had, they are not related to HIV since you had zero risk for HIV. You don't need any more tests, and you can forget about this event and move on.
