Hi. First, I would like to apologize for a very lengthy post. I'm not sure if I'm in the correct forum but I'm hoping you guys can help me.
I tested non-reactive on an Ag/Ab test 20 days and 27 days after a sexual encounter. This was considered good as conclusive so I asked my doctor if I can be put on PrEP as an additional protection for future possible encounters. I started PrEP on the same day (Day 27). However, the following day, I woke up with slight muscle aches and headache, and a feverish feeling. These did not last long and was gone even before the day ended. The following day, the back of my thigh was extremely itchy and sometimes had a burning sensation. These were gone the following day.
At that point, I wanted to make sure so I took two more Ag/Ab tests - one on Day 29, another on Day 36 (counted from the day of the original encounter). These tests were done while I was already on PrEP. Both were non-reactive.
With my scenario, I hope you can help me with my questions:
1.Were my 20 and 27-day tests really conclusive despite the symptoms that showed up the day after? I know that 28 days is conclusive (as per a lot of experts) but Dr. Tan's website (a prominent doctor in SG) even suggests that he's very confident when someone tests negative at 2 weeks and a 3 week test is already a very strong indication that an infection has not occured.
2.If the result wasn't conclusive on Day 27, then the tests on Day 29 and Day 36 should be, correct? Or will there be a delay in the detection since I started PrEP on Day 27?
3.Will PrEP affect the window period for detection? I want to get tested again (45 days after the original encounter) but I don't know whether I can trust that result since I don't know whether my daily adherence to PrEP may have an effect on the window period for detection.
I'm sure that most of you will probably tell me to consult with my physician and believe me, I want to. But she's currently out of the country and won't be back until next month so I'm hoping that in the meantime, the experts on this forum can help me with my questions.
I would really appreciate any input that you guys can give me.
