HIV testing accuracy

I just received a text a few days ago from a woman I had unprotected sex with almost 16 weeks ago who informed me she just recently tested positive for HIV.  Fortunately for these questions I know the exact date of key events. According to her she contracted it about three weeks prior to us having sex which puts her at a highly infectious state. The week after being with me she came down with ars. Six weeks and one day after our encounter i got tested 4th gen duo negative. The day after taking my test I got a 5 day intense flu like illness. A few days ago I did two oraquick oral swab tests after she texted me both of which were negative. I am scheduled for an appointment on Monday to get another lab test where I will be almost 16 weeks out. My concern is that if I was a late seroconverter and got ars the day after my 6 week 4th gen test then the antibody portion of that test is not reliable. That leaves the p24 portion and through my research testing for p24 only has a 55-75% level of accuracy. That would leave the oral swabs which have only a 92% level in detecting positives. Also I have been taking 500mg valtrex daily for sometime. I read older posts that say valtrex doesn't affect testing. But very recent studies show it reduces viral load by 50%. Shouldn't this have an effect on testing?
