my vagina is really really itchy during my period, mainly towards the end. it is so itchy i cant sleep and cant stop itching. i have tried different thrush treatments (cream, tablet, pessary) but none of them worked. i also tried this bv treatment called balance active which works but only short term, so it returns every period! i also tried bv antibiotics but these also worked only short term, and after a few months i became immune to them! is there anything else i can try? i also smell a bit fishy :(
