Re: condom broke
Well you dont need to look for symptoms as they will never prove your status,infact it only ever creates fear for nothing. If and thats a big if, she had HIV then a one time exposure like this is classes as low risk. In terms of testing you need to test at 3 months for a conclusive result, but a test at 6 weeks will be a very good indication of your status.
Sex workers use condoms to protect themselves from HIV, so its unlikley she would have HIV.
Hope that helps
