Is A PCR Test Done Post 37 Days Of Exposure Conclusive?

Question: I have unprotected vaginal sex 2 months ago. on 9th day I started to have bitter tongue in morning with white tongue and dry mouth. oral temperature of 99.5 and persistent headache and burning eyes. all these are continuing till date .
I did antibody test at 23rd day and PCR TEST at 37th day and combo test on 51st day. all came negative and undetectable. but still I am scared as all these symptoms are related to HIV as given in Internet.
in spite of these, there are couple of questions which I want to ask which might give me some strength
1) if my symptoms are due to HIV, aren't they bound to get detected in test
2) how long can these virus or antibody remain undetectable as my last test was 51st day. have you ever witnessed a case where a seven weeks post negetive patient has turned positive after 12th weeks or after that
please help. attaching my tongue photo

Dear XXXX,
Welcome to HCM.
If your symptoms are related to HIV then the virus id definitely detectable in combo or PCR test after 15 days and the results are negative so nothing to worry at all because you are absolutely risk free.
It is also not possible that the result being changed to positive at 12 weeks after having negative result at 7 weeks so don't get scared or so anxious about HIV and forget about the incidence completely.
The more you think or read about HIV the more you get tensed or anxious which will further hamper ur health so get your self relaxed and move on in life. Always stay happy and healthy ahead.
