What is the ruling for a woman whose menstruation stopped for a period, then she saw something brown in color, and she does not know the time of her usual cycle?

Question:
Honorable Shaykh, the questioner says: A woman’s menstruation stopped for several months. Then she noticed that something was coming out of her, brown in color, close to black, and she does not know the time of her usual cycle, so what should she do? It is known that it stopped for her, then it returned to her a second time.

Answer:
As you heard, if her menstruation returns to her, even if it is light, she sits for the days of her usual cycle that she used to know, then she performs the full ritual bath and prays when it ends. Because the dark discharge and the yellowish discharge during the time of the custom are menstruation, as the scholars say, and by the saying , it indicates that during the time of menstruation it is considered something. So if the dark discharge and the yellowish discharge come during the time of menstruation, she considers them to be menstruation. Yes.
