What is the ruling on prayer and fasting for a woman who uses a contraceptive that causes prolonged bleeding (three weeks), with a short period of purity (less than two weeks), and is this blood considered menses or istihadah (non-menstrual vaginal bleeding)?

We previously discussed how a woman who uses an IUD and experiences a disrupted menstrual cycle, exceeding fifteen days, should manage her situation. It is advisable not to use an IUD unless absolutely necessary, as it can cause menstrual irregularities and lead the woman into doubt and confusion regarding the timing of her acts of worship. This is what Sheikh Ibn Uthaymeen, may Allah have mercy on him, indicated concerning birth control pills, as they are similar to the IUD in causing disruption. If it is possible to remove the IUD without harm, then it is better to remove it to get rid of this irregularity.
