The ruling on extending the days of menstruation and irregular bleeding

Question:
What is the ruling on menstruation, or what should one do? Please inform us. May Allah reward you with good.

Answer:
When women differ and the number of days increases, it is obligatory for her to wait until the usual period ends and she sees purity. When she sees purity, she performs the full ritual bath, prays, fasts, and becomes lawful to her husband. When the usual period ends, she sits and does not pray. The usual period may be six days, and she may see blood for seven or eight days; there is nothing wrong with that. The usual period increases and decreases. It may be six days, and she may become pure after five or four days; she performs the full ritual bath and prays even if the usual period has decreased, because the usual period increases and decreases. However, if the usual period continues for fifteen days, that is the limit. If it exceeds that, she is a woman with irregular non-menstrual bleeding. She performs the full ritual bath and prays even if blood is present, and she returns to her original usual period, which is six or seven days, because when it exceeds fifteen days, it is known that this is an illness and that this is not the usual period but rather irregular non-menstrual bleeding. She returns to her original usual period, which is six, seven, eight, or five days, and she prays and fasts for what exceeds that, and she becomes lawful to her husband. If she broke her fast, she makes up what she missed in Ramadan. Purity is indicated by the white cloth or…
…a piece of clean cloth. If she sees that it has changed with blood, then she has not become pure. If she sees it clean with nothing on it, then she has become pure. The maximum duration of menstruation is fifteen days. This is its maximum. If it exceeds that, it is a sign of irregular non-menstrual bleeding. She returns to her original usual period: five, six, seven, or eight days. Yes.
