You have no risk of HIV, gonorrhea, chlamydia, mycoplasma genitalium, trich, or NGU. All of those require penetration, and you had none.
You can get herpes, syphilis and HPV from genital to genital rubbing/grinding. You don't mention if she did any grinding, or if she was just sitting on you.
None of your symptoms sound like any STD. It sounds like the flu or some other upper respiratory illness. I wouldn't worry about STDs if I were you.
