If you had a negative result at 9 months, yes that is conclusive.
From unprotected sex you risk getting every STD. I can not say what if any STD the prostitute had but if she did have anything you were at risk.
I would advise getting tested.

Yes you can get STD's from that encounter. Was it protected sex?
