Vaginal discharge

As Salaamualaikum

A woman suffers from vaginal discharge and is Mazoor. Every month after bleeding for a 7 days she then has discharge which is brownish and then yellowish. She baths after 10 days. After the 10 days, on some months the yellowish color continues for 1 or 2 days. On some months the yellow color disappears after the bath on the 10th day. When should the woman bath, is after 10 days correct? She can no longer remember her habit before she became Mazoor. Please advise.

Jazakallah
