Must the woman make up the days when she bathed after her menstrual bleeding stopped, then the bleeding resumed, or is expiation required of her?

When a woman sees purity, she must promptly perform ghusl (ritual bath). If bleeding resumes, she must refrain from prayer and similar acts until the bleeding stops, then perform ghusl again, as long as this occurs within the menstruation period. As for the questioner's action of not performing ghusl after the bleeding resumed, it is an error. She must make up the fast of the day she saw blood, because her fast was not valid. As for the days that followed, her fast during them is valid because ghusl from menstruation is not a condition for the validity of fasting. She must also make up the prayers she performed without ghusl, because they were not valid due to the lack of the condition of purity.
