A Change in the Routine Number of Days of Haidh

1. A woman has a regular period of 4 days haidh. Then one month she had 5 days of haidh. The next month bleeding was for 15 days. 5 days of these 15 days are haidh and the rest istihaadhah.
2. The first routine cycle of 4 days are of no consequence. The cycle changed to 5 days.
3. In the above case (1) when the bleeding continues for more than her set number of days (that is 5), then she should wait till the tenth day for the bleeding to stop.
4. Now since the bleeding did not stop, it continued for more than 10 days, she should therefore take a bath and make Qadha of 5 days Salaat and start performing her Ada (current) Salaat.
