It's just started a few days ago - a sort of lingering odour - I notice it more at night when am cuddling up to her to say goodnight - her mouth/hands smell fishy. I thought she might have a urinary infection but her vagina doesn't smell, it's her skin it seems. I googled it and now worried she has fish odour syndrome - DH says I am being silly and that it's her toothpaste. Does anyone know anything about this?
