Change in Aadat/Cycle

1. The aadat/cycle can change in haidh and nifaas.
2. Even if the change took place just once, the change will be considered the new aadat or pattern.
3. Example in haidh: The previous month the haidh lasted for 5 days. This month it was 6 days. The aadat has changed and is now 6 days.
4. Example in nifaas: After her first birth she bled for 25 days. After the delivery of her second child, she bled for 30 days. The aadat in nifaas has thus changed to 30 days.
5. Similarly, if you have a set number of days of tuhr, for example 15 days in haidh, and then one happens to go 20 days clean before haidh started again, it will be said that the aadat in tuhr has now changed to 20 days.
