What the evidence says
Normal vaginal discharge is clear to white, changes in amount and texture across the cycle, and every woman has her own normal smell. None of that is a hygiene failure. The douching myth runs exactly backwards: the vagina cleans itself, and douching upsets the protective bacteria that keep its environment stable.
Clinical guidance separates normal from not: discharge with a fishy or foul smell; grey, green, frothy or cottage-cheese-like discharge; or discharge with itching, burning or bleeding is worth seeing a clinician about. Douching upsets the balance of the protective bacteria, and in a study that followed 3,620 women for a year, regular douching came with a modestly higher risk of bacterial vaginosis (relative risk 1.21). The vagina cleans itself; the vulva needs only water or a mild unperfumed wash.
What this does not show
The abnormal list tells you when to be seen, and it diagnoses nothing: the same feature can belong to different infections with different treatments, which is why a description is not enough to treat from. 'Your own normal smell' is the key phrase. What matters is change from your baseline, not comparison with anyone else. The condition itself is not known to change discharge; nothing here links the two.
