What is the ruling on continuous yellow discharge after the end of menstruation, and is ghusl required for it?

Yellowish discharge connected to menstrual blood is considered menstruation. A woman should not rush until she sees the sign of purity, either complete dryness of the area or the discharge of white seminal fluid, unless the total days of menstruation exceed fifteen days. If it exceeds this period, she must perform ghusl (definition) (ritual bath) and pray, even if the discharge or explicit blood continues; because the maximum duration of menstruation is fifteen days, and anything beyond that is considered istihada (non-menstrual vaginal bleeding).
