My vagina has been very itchy and irritated the past couple of weeks with some irregular discharge. it can also smell quite fishy? is it an infection?

Yeast? BV? STD?: Any new, unexplained vaginal discharge should be professionally evaluated.Your symptoms overlap between those typical for a vaginal yeast infection (itching, irritation) and bacterial vaginosis (increased discharge, fishy odor). BV is overgrowth of mostly normal vaginal bacteria. Neither BV nor yeast is usuaally sexually transmitted, but STDs are common in women with BV. Get examined ASAP.
