Is there anything incumbent upon me due to not performing ghusl after the cessation of my menstrual cycle for more than 10 years?

A woman knows she has become pure by one of two signs: dryness or the white discharge. If she sees purity by dryness, meaning she inserts a cotton swab and it comes out clean with no trace of blood, yellowish discharge (ṣufra), or brownish discharge (kudra), then she should immediately perform ghusl (ritual bath). She is obliged to make up the prayers missed from past years if she was aware of the time of purity. If she does not precisely know their number, she should continue making them up until she is reasonably certain that her obligation has been fulfilled. However, if she was excused due to ignorance, Shaykh al-Islam Ibn Taymiyyah chose the opinion that she is not obligated to make them up.
