Vaginal discharge smells like fish eww help me?

No need to panic just yet as it sounds like thrush. Try some natural greek yoghurt or a tablet from the chemist will sort you out in no time. Doctor would advise you to get rid of any tight fitting pants and lycra underwear as cotton does not harbour as much bacteria that harbours nasty smells. Thrush does not always mean burning or itching just that you suffer less symptoms,
