Your symptoms suggest possible infection, especially if the discharge is real, and not mucus you squeezed out by repeated checking. But the exposure was very low risk (see multiple other threads on the risk of STD from oral sex). In any case, do not rely on anybody's online opinion and advice. If you think your symptoms are real, get heatlh care. A good place to start would be your local health dept STD clinic.
