Is it obligatory to purify clothes when yellow discharge, which cannot be removed by water, comes out between the labia?

What a woman sees of yellowish or brownish discharge is considered impure and menstrual if it occurs during the period of her regular menses or if it is connected to blood. Clothes and body must be purified if the yellowish discharge gets on them. However, the inner part of the vagina does not need to be washed, only what becomes visible when relieving oneself. It is advisable to disregard obsessive thoughts if they are present.
