What is the ruling regarding the presence of a slight spot of blood in the middle of the usual menstrual period, followed by yellowish and brownish discharge after an unaccustomed purity, and what is the ruling regarding the non-continuation of bleeding during this period, and must prayers be made up from the fifth day until the day of purity?

A woman recognizes purity by one of two signs: dryness or the white discharge. If she sees purity by one of these two signs, she must perform ghusl immediately. If she is affected by obsessive doubts (waswasa) or finds it difficult, she may follow the opinion of those who permit waiting half a day or a full day to confirm purity. If she sees blood after purity and ghusl, she returns to a state of menstruation. However, yellowish or brownish discharge after purity is not considered menstruation. When in doubt about the occurrence of purity, the default is that it has not occurred. A woman must ignore obsessive doubts because indulging in them leads to great evil.
