Is it obligatory to make up prayers that were missed due to continued cessation beyond the menstruation period for extra days, assuming it was still ongoing due to natural yellowish discharges and the difficulty of seeing the white discharge?

If a woman is certain of purity by one of its two signs (dryness or the white discharge), she must perform ghusl and prayer immediately. Anyone who delays ghusl while in this state is negligent. However, if she doubts whether purity has occurred, the default is that menstruation persists, and nothing is incumbent upon her. If she becomes certain of purity but abandons prayer, thinking she is still menstruating, then according to the majority of scholars, she must make up the missed prayers, and this is the more cautious approach. However, Shaykh al-Islam Ibn Taymiyyah holds that making up prayers is not obligatory in this case.
