What should a wife do if she has been experiencing light bleeding for 25 days after her period came ten days earlier than usual due to forgetting a birth control pill, and the bleeding has continued despite the doctor's advice to take cycle-regulating pills to stop the bleeding?

A woman's menstrual period cannot last two months. In this case, your wife is experiencing irregular bleeding (istihada). She should consider the days of her usual period as menstruation, then perform ghusl (ritual bath) and resume prayer, fasting, and marital relations. She is considered pure even if blood continues to flow.
