Am I At Risk Of HIV After Unprotected Sex With A Man On PrEP Who Is HIV-negative?

Hello, I am a gay male. I usually always wear condoms when I have sex, last night I had sex with a man who said he is Hiv-negative and has been on PREP for a while now. We didn’t use a condom. I know that the chances are low but I am kind of getting anxious and hoping I don’t get HIV. Am I safe? Thank you!
