ok this may be tmi but does it sorta smell like a rubbish tip? if so its a overload in your hormones which is causing too much discharge hence the smell...you need antibiotics to get rid of it otherwise it will remain there....i used to get that problem around the end of my period cause my hormones were just all over the place...so far so good i havent had it back...its basically a form of thrush but without the itchiness. hope this helps.
