hi ! you have said that you checked with p24,
HIV 1 and HIV 2, and are nrml, that too after 6 weeks, generally they should be checked before 4 weeks, now having checked and are nrml, but you said you have symptoms of throat pain and rashes, based on these we cannot conclude your +/- of the test, just wait for 3 mnths and go for ANTIBODY tests which confirms the diagnosis very well. mean while take treatment for throat trouble and rashes and observe for any new symptoms. if these get better and doesnt reappear you need not worrry about it.
