Oral thrush 8 weeks after potential hiv exposure, 4 weeks after pep. will test in 4 days. should i prepare for hiv+ result because of the oral thrush?

Probably not, but...: ...it depends on how high the risk was from the exposure you are concerned about. But even the highest risk exposures usually don't transmit HIV, and with PEP the chance you were infected is near zero. As for oral thrush, maybe you don't have it: for example, white coated tongue isn't the same thing. Anyway, thrush rarely occurs with early HIV infection.
