The Ruling of Intermittent Menstruation

If a woman sees menstrual blood on a day and purity on another her situation is either of the following:

a. The blood flows continuously from her without stopping.

This is a condition known as Al-Istihadhah.

b. The flow of the blood is discontinuous or intermittent.

If the flow of blood ceases sometimes and runs at other times, then its ruling is as follows:

i. If the blood flow stops for less than a day, that day is counted as part of a menstrual period.

ii. If she sees what indicates purity (e.g. a whitish discharge) at this time, this is considered the end of menstruation. She then is regarded as being pure, regardless of whether the blood has stopped recently or a long time ago, or it stopped more or less than a day ago.
