How does a woman pray if menstruation continues for more than a month?

If a woman's menstrual bleeding exceeds her usual period, she is considered to be in a state of menstruation (hayd) as long as her bleeding does not exceed fifteen days. If it exceeds fifteen days, she becomes a woman with irregular bleeding (mustahadah). In this case, she should perform a ritual bath (ghusl), pray, and perform ablution (wudu') for each prayer. If this recurs, she should observe her usual period and consider the remainder as irregular bleeding. Otherwise, she should differentiate based on the blood's characteristics (distinguishing between menstrual and non-menstrual blood). If that is not possible, she should follow the prevalent custom of women in her family. It is obligatory to make up the prayers missed during the days she considered herself menstruating, but which were in fact irregular bleeding.
