Since around day 80 I have been having night sweats every night - not ones that drench clothing but ones that make my forehead and neck sweat.

I’m not sure I’ve had any other issues to this point as anxiety about results has been a huge concern and I didn’t sleep for 3 days awaiting the result for my 81 day test.

Should I be testing again?

One of the most common themes on this forum -- repeated innumerable times -- is that the antigen-antibody (AgAb) HIV blood tests are among the most accurate diagnostic tests ever developed, for any medical condition. When done sufficiently long after the last possible exposure (usually 4 weeks and always by 6 weeks), the results always overrule all other considerations:  no matter how high the risk of HIV at the time of exposure, and no matter what symptoms may be present, the test result rules. Your results are to be believed -- not yoru night sweats. Your 60 day test was conclusive (it could have been at 42 days) and the 81 day test unnecessary. You certainly do not need any additional tests.

I'll also point out that your exposure was low risk, since heterosexually transmitted HIV is exceedingly rare in Australia. (Of course you still should have used a condom -- but the risk was far higher for other STIs than for HIV.) In addition, your symptom onset was far too late to be due to new HIV from that event, and night sweats alone would never be caused by HIV. In any case, the negative test results are to be believed; you definitely did not catch HIV. If night sweats or other symptoms continue, see a physician -- but not because of any concern about HIV.

I hope these comments are helpful. Let me know if anything isn't clear.
