Is pale or turbid discharge that appears two or four days before the menstrual period due considered menses that prohibits prayer and fasting?

Any blood a woman sees during a time when it is possible for it to be menstruation is considered menses, regardless of whether its color is black or otherwise. So, if a woman sees blood a few days before her usual period, it is menstruation, and she must stop praying, fasting, and all other things a menstruating woman abstains from. The yellowish and brownish discharges connected to this blood are also considered menstruation. This blood must be considered menses as long as it is seen during a time when menstruation is possible.
