women only correctly self diagnose vaginal yeast infections 1/3 of the time. really not worth self treating unless you have a history of yeast infections are good at knowing the symptoms of them.
You need to go and be seen monday and get a proper work up done. if you are still using otc yeast treatments, stop them now so that they are gone from your vagina so that your provider can get a good sample to look for other causes. if you've had unprotected sex and haven't been tested recently for std's, discuss with your provider which ones you need screened for and when.

Yes it could be a STD like chlamydia and medication you took could have masked the symptoms. If the sex with those 2 people were protected then I would think this is yeast or BV. If unprotected then still think one of those as my top choices but chlamydia and Trich might also be a possibility.
