Asking for a friend? 

It depends completely on what kind of sex you had. I think it's actually pretty low generally, but the consequences are very high obvs. Either way you absolutely must get tested, it will put your heart at ease to know the answer with certainty, and you have to know if you carry a risk to other sexual partners.
