PEP is generally recommended for instances where the partner is known to be a confirmed positive.
You did put your self at some risk. However, the reassurance your partner has provided can't be ignored since most people won't lie so blatantly.
You could just take a test at 28 days with a IV Generation of HIV test and move on. I am assuming this is an hetrosexual encounter, therefore, the risk is minimal.
I believe you are outside the window to start PEP at this point. And it's a pretty toxic drug so it isn't given for any exposure. You've normally engaged in protected sex with the guy showing that he normally uses condoms as you do. Quite doubtful that he has HIV. But go ahead and get tested as Mike suggests at 28 days and beyond. I would not bother with worrying about PEP. All the odds are that you will not have HIV.
Spoke with my PCP, she recommended I take it, starting ASAP. She went ahead and did an HIV test which I am freaking out about because I was with someone prior (also told me he was "fine"), so we'll see what happens.
You can obtain a conclusive result only after 28 days from the last dose of your PEP medication with a IV / V generation HIV test.
PEP can interfere with test results. That's why you need to have ceased PEP for 28 days prior to taking the test.
