A women bleeding continuously will count the menstruation days according to her last schedule i.e. the days of menstruation cycle before this disease will be counted as the menstruation days after the disease. During these days, she will not offer prayers, while in rest of the days after having bath after menstruation will she offer every prayer with wudhu. With one wudhu, she can pray as much salah as she can, provided there happens no other thing which nullifies the wudhu.
Allah (Subhana Wa Ta’ala) knows Best
