hpv from oral

Hopefully someone can help me out. In a nut-shell...I gave and recieved oral from a girl in july 08 and again in november of 08. She told me she had the strain of hiv which could lead to cervical cancer but that at her last gyno appt. her doctor said it was gone. Assuming she lied and did have the strain that causes warts, how risky was my activity? It has been almost 4 months since the november exposure and almost nine months since july. I haven't had any warts or symptoms at all.

is it possible that I did not contract hpv from her?
