You need to do your own test. If you can take a 4th generation test (antigen/antibody test) at least 28 days after your encounter, you can consider the result conclusive. Having intercourse with a sex worker who is willing to let you penetrate without a condom is an unsafe practice, because she probably lets other men have unprotected intercourse with her, too.
Do not rely on someone else's test to determine your own status. 14 days post-event is also not conclusive for any HIV test.
