What is the ruling on prayer and fasting during days exceeding the usual duration of menstruation after inserting an IUD?

If a woman's menstrual period increases after the insertion of an IUD, this increase is considered menstruation, which prohibits prayer and fasting until purity. Sheikh Ibn Uthaymeen issued a fatwa that a woman does not have to make up prayers if she causes menstruation to start, as the ruling revolves around the presence or absence of menstrual blood.
