How To Calculate My Light Period and Heavy Irregular Bleeding?

Hanafi Fiqh

Answered by Mawlana Ilyas Patel


My periods have started regulating recently after having irregular periods for so many months and bleeding in between periods.
This has complicated it, but I usually bleed for ten days, which is my habit. The way my cycles usually appear is a very light spotting that lasts nearly six days. After that, I get a heavier flow of my period that lasts almost eight days.

This month I started my period after a 28-day gap in this manner, and now that the bleeding has continued for even longer than ten days, I am in a state of irregular bleeding, which is quite heavy. I find it difficult praying with the heavy bleeding as well as it feels like this is my actual period, and it feels like it is hard to judge.


In the Name of Allah, the Most Merciful and Compassionate

Your period will be based on your regular menstrual habit, which is ten days. If the bleeding continues for more than ten days, then the number of days beyond your habit is considered irregular bleeding (istihada). So you will start praying as normal from day 11 onwards.
