Is PEP Effective If Taken 24 Hours After Exposure?

Dear Doctor, 2 months ago I had anal sex with a girl I met, the condom broke and after 24 hours I took pep for 28 days, I did a 4th gen test 3 weeks after I was done with pep, it was negative. How accurate is this result? I have been really worried, thanks for answering my question.
