What is the ruling regarding my prayers which I used to perform out of ignorance, not knowing about the white discharge and the secretions preceding blood, which I now consider to be menstruation?

What a woman sees before the onset of blood, such as yellowish or brownish discharge, is not considered menstruation. However, if it appears after the onset of blood and is connected to it, then it is menstruation. But if it appears after seeing purity, it is not considered menstruation. Prayer must be abandoned upon seeing blood and any connected yellowish or brownish discharge. There is no need to make up the prayers that a woman missed due to yellowish discharge after seeing purity.
