What is the ruling on blood that descends in the form of drops, then a brownish liquid, then blood accompanied by pain, then a brownish and yellowish liquid, given that menstruation occurs twice a month and the sign of the white discharge (al-qassah al-bayda') does not appear, and what should the questioner do in this case?

You are considered to be in menstruation if you observe menstrual bleeding for approximately fourteen days, the first seven of which are light spotting, followed by blood and brown discharge. This is because the maximum duration of menstruation, according to the majority of scholars, is fifteen days. Brownish and yellowish discharges immediately following the menstrual period are considered part of menstruation, as long as the total duration does not exceed fifteen days. If you observe purity by dryness within this period, then perform ghusl and pray. You are considered to be in menstruation until the blood ceases, along with any associated yellowish or brownish discharge, as long as the total duration does not exceed fifteen days. If the blood stops and you observe dryness, then you have attained purity thereby, provided that your period of purity lasts for fifteen days, because the minimum period of purity between two menstruations, according to the majority of scholars, is fifteen days, and according to the Hanbalis, it is thirteen days.
