I had unprotected sex so I went to the hospital on 7/12 and was instructed to take pep at hour 57, I planned to have 12 weeks to be tested for 84 days but I'm so stressed and today is 74 days after the risk i getting hiv combo test, the result is negative in s/co 0.04 , is this peace of mind, should i be worried, i'm afraid pep slows down the production of antigens and antibodies so it's not accurate
