What is the ruling on blood coming out a few days before the expected time of the monthly period?

Question : The questioner says: Honorable Shaykh, the interval between the two periods is twenty-two days. Four or five days before the period comes, a small amount of blood that is not significant appears, and this continues until the time of the normal period. Is this considered part of the days of the period? Does it invalidate the prayer and the fast? Please inform us clearly. May Allah reward you with good.

Answer : One looks at this blood or these drops of blood to see if the woman finds the usual pains of menstruation. If so, then these drops are the beginning of menstruation, and it is not permissible for the woman to pray or to fast. But if these drops come after complete purity, but they have occurred to her, then they do not harm.
