Welcome to our Forum. I'll be glad to comment.  This risk for acquiring HIV from the exposure you describe is very low.  The majority of commercial sex workers do not have HIV and even if your partner did have untreated HIV, the risk for acquisition of infection from a single exposure of the sort you describe is less than 1 infection in 1,200 encounters(in other words, 99.9% of exposures will not lead to infection).  Your negative tests make it far more unlikely that you acquired HIV.  At three weeks after exposure (your most recent test) combination HIV antigen/antibody tests would detect about 90% of recent infections and still more would be detected by the HIV RNA test.  This I would now estimate that your risk for infection is less than 1 in several million, at most and personally would have no further concerns what so ever.  If you wish to be absolutely sure that you were not infected, my advice would be to test again with the combination test 6 weeks after the exposure (on February 2 or beyond). At that time results will be entirely conclusive.  Should you choose to test again (personally, as I said above, I would not bother), I am confident that the test will be negative, proving that you were not infected.  

I hope this information and advice is helpful.  EWH  

06/Jan/19 HIV 1&2 and p24 combo test.  Results negative and non reactive

I'm surprised that you felt the need to ask this question again since it was answered earlier.  As I told you earlier, for all practical purposes you had conclusive results 13 days ago when I last responded, now they are "official".  Thus, the answer has not changed- you have proven that you were not infected with HIV.  There is no need for further testing.  To do so would be a waste of your time and money.

This completes this thread which will be closed shortly without further answers.  I hope that you will be able to move forward without continuing concerns.  EWH
