When Bleeding Lasts for More Than Ten Days
Issue No.470- If a woman with a timely fixed period sees blood for more than ten days, and is unable to determine the days of ḥayḍ through its signs, she should consider the number of the days of the menstrual period of her kinswomen (whether paternal or maternal, living or dead) as that of her own, provided that almost all of them have the same period. However, if they are different in their periods, for example, some of them discharge blood for five days while others discharge blood for eight days, the obligatory precaution is to consider seven days in every month as the days of her menstrual period.
