All perfect praise be to Allah, The Lord of the Worlds. I testify that there is none worthy of worship except Allah, and that Muhammad is His slave and Messenger.
As long as your bleeding is continuous, you have to follow these steps: clean yourself from impurity, use an absorbent, perform ablution and then perform each prayer at its fixed time, even if the bleeding continues during the Prayer since it is a necessity. You may combine the Thuhr with 'Asr Prayer at their time, and Maghrib with 'Ishaa’ Prayer at the time of one of them. You must not leave offering prayers except in those days when you used to have your monthly period before having the problem of continues bleeding. If your menstrual period was seven days, then you should give up praying seven days, if the period was six days then, you should leave prayers only for that period and so on.
For more benefit on the difference between monthly menses and bleeding outside the monthly menses, please refer to Fataawa 129256, 199375, 192925, 183343, 154565 and 145201.
For more benefit on seeing white, reddish or brownish discharges after the end of menses, please refer to Fatwa 100850, 174955 and 231715.
Allah knows best.
