Relax. There has never been a proved case of HIV that was acquired by performing cunnilingus. See many other threads on this; search the STD Forum threads and archivies for "HIV transmission risk", "oral sex", and "cunnlingus". The large majority of female sex workers are not infected with HIV, but your risk was zero even if she was. You have nothing to worry about and do not need testing.
