Misgivings about discharge on the floor

Dear questioner,
Thank you for your important question.
May Allah, Most High, reward you for your desire to increase in knowledge.
The white or clear discharge does not necessitate ghusl. If your menstrual cycle is generally around 5 days, then your initial ghusl is sufficient.
The floor is considered pure as long as you don’t see any impurity. There is no need to worry about your towel dropping on the floor.
(Shurunbulali, Maraqi al-Falah)
These are all misgivings. Ignore them and pay them no attention. The remembrance of Allah, Most High, helps in repelling misgivings. Consider reading a daily litany of Prophetic Prayers such as the Wird al Latif.
And Allah alone knows best,
