i get white patches or whitish dry skin on my labia after i finish my periods. this has been like the third time its happening, no itch, no smell, just that dry white patches which sometimes peels when i pull the skin. however, the condition vanishes when i'm about to get my periods and i get my normal skin back, but just after my period ends, it comes back!! i tried to apply clobetasol the first time but didn't help. i now apply coconut oil. what could this be and how can i get rid of this.
