wow...i'm surprised a doctor would start you on PEP for the situation you are describing.
If you were prescribed PEP, keep on it unless otherwise advised by your doctor. You had a possible exposure. After PEP, test at 3 months for conclusive. Don't have sex in the meantime, and if you can't control yourself be sure to wrap it up.
It's harder for a woman to transmit to male than vice versa, and you don't even know if she was infected in the first place. You could find her and ask her to get tested to determine if there was a risk, but if she were positive, you'll still need to wait for the 3 month test for conclusive result as to your status.
