Irregular Bleeding

1. A woman does not have a fixed number of days for haidh. Sometimes it is 4 days, sometimes 7 days. In this manner it changes. Sometimes she experiences a full 10 days of haidh. All these days are haidh.
2. If a woman whose number of days of haidh changes experiences bleeding for more than 10 days, she should see how much days of haidh she had the previous month.
3. The previous month’s number of days will be her number of days of haidh for the month in which the bleeding exceeded 10 days, and the rest will be istihaadhah.
