i've been having dry, flaky and itchy vagina for over a year now. i also have a discharge, there are days that it is heavy and greenish but most of the time it's just white and not heavy..it usually gets worse few days before or after my period..i've only had one partner and we only have sex like once a month..i'm actually scared to do it with him because it's painful, it feels like he's tearing my vagina...i don't experience any pain when i pee...do i have STD, yeast infection, hormonal imbalance or hypothyroidism? i'm really worried..hel me pls..
