What is the ruling regarding the obligatory prayers for me if I performed ghusl and prayed on the eighth day after my bleeding stopped, and I did not wait for the white discharge (al-qassah al-bayda’) which appeared later, knowing that I did not pray Fajr prayer nor the prayers of the seventh day? And is what I did correct?

A woman recognizes her state of purity by the cessation of menstruation, either by dryness (al-jufūf) or by the white discharge (al-qaṣṣah al-bayḍā’). Whenever she observes one of these two signs, she is obligated to promptly perform ghusl (ritual bath). If she delays performing ghusl after seeing dryness, she is required to make up all the prayers she missed after her purity began and before she performed ghusl.
