Faṭimah: If the intensity of bleeding decreases on the sixth or seventh day and turns into spotting, such that every time a woman checks herself, the cotton is stained with pink or yellow spots, what is the ruling on this?

Mother: Spotting at the end of the menstrual period is still considered part of menstruation, even if the blood is very little and has turned yellow or pink. If the bleeding completely stops before the tenth day, all of this blood is considered menstruation. However, if the spotting continues beyond the tenth day, where every time she checks herself, the cotton is stained with light yellow or pink spots, there are two scenarios:

If she has a fixed time and duration cycle, or only a fixed duration cycle, she should consider the number of days of her usual cycle as menstruation, and the rest as Istiḥāḍa. For example, if her usual cycle is six days, she should consider the first six days as menstruation and the remaining four days as Istiḥāḍa. Therefore, she must make up the prayers missed during these four days.
If she is a Mubtadiʾa (first-time menstruation) or has a fixed time cycle, she should follow the cycle of one of her close female relatives.
