What is the ruling on the prayer of a breastfeeding woman whose menstrual cycle is irregular, and she experiences spotting, clear blood, and yellowish discharge, knowing that her usual period is 6 or 7 days?

If the total duration of blood, yellowness, and turbidity reaches a day and a night, then it is menstruation that necessitates abandoning prayer and fasting. Upon their cessation, ghusl (ritual bath) and prayer become obligatory. If the blood returns, the woman becomes menstruating again. As for yellowness and turbidity not connected to blood, they are considered menstruation if they occur during the usual period. If she performs ghusl after the cessation of blood and any accompanying yellowness or turbidity, she is pure. If the duration of blood and what is connected to it exceeds fifteen days, or if the total of these discharges does not reach a day and a night, then it is considered istihadah (non-menstrual bleeding).
