Must I pray or not pray if I bathed on the eighth day of my menses, then blood appeared after the IUD was inserted, and after four days, yellow or transparent discharge appeared? And is the menses considered to have returned if yellow discharge appears after dryness or transparent discharge on the fourteenth day, and before 15 days have passed?

If the blood after purification from menses and the insertion of an IUD is due to the IUD, or if there are yellowish discharges after purification, then it is not considered menses and does not prevent prayer. The woman must make up for the prayers she missed. However, if the blood is not due to the IUD, then it is considered part of the menses and completes the first menses, and likewise for the yellowish discharges connected to it, as long as it does not exceed 15 days.
