I Could Have Been Exposed To Hiv By The Following

I could have been exposed to hiv by the following way:
I had unprotected oral and vaginal sex for like 10 minutes. The girl told me that she did not have HIV or any other STDS. She did not have any sore signs or post sore spots in her vagina or body. She looked relatively healthy. What are the chances that I caught HIV or any other std. Its been a week and I don't have any symptoms at all on my body.
