I agree, and I'd be far more worried about strep or tonsillitis than an std in the throat.
calm down..you are freaking yourself out.
first- if you had safe sex, which you said you did and you didnt give any oral than you are worrying about 2 things that are not related.
second- it is flu/cold season...this may just be that.
calm down, if you are truly worried go to the dr. and you can keep this from your folks, just go to a clinic they dont share your information with family.
