Is fasting and prayer obligatory during the menstrual period that extends for 7 days, then light red blood appears after the cessation of purity, followed by a brown discharge that lasts for 3 days, and is it obligatory to make up for the missed fasts during this period?

If a woman sees the sign of purity from menstruation, she must perform ghusl and pray. Her fasting during the period of purity is valid. If the blood returns after that, she is considered menstruating again, as long as it returns within a period suitable for menstruation (fifteen days is the maximum duration for menstruation). If this blood ceases, she must perform ghusl again. The yellowish and brownish discharges connected to the blood are considered menstruation. However, if they appear after the cessation of blood and outside the customary period, they are considered purity, and she must do what a woman with istihadah (non-menstrual bleeding) does. The days a woman fasted while menstruating must be made up, whereas the days she fasted while pure are valid.
