What should a woman do whose period typically lasts seven days, but who saw brown discharge on the eighth and ninth days? And should she perform ghusl and make up the missed prayers?

A woman recognizes purity by one of two signs: dryness or the white discharge. Yellowish and brownish discharges connected to blood are considered menstruation. If the discharges are connected to blood and purity has not been observed, the woman is still menstruating and must wait until she sees purity by one of its two signs. Then she should perform ghusl and pray, even if this exceeds her usual period, as long as it is within the time frame possible for menstruation.
