Question 80) - Are there minimum and maximum periods of purity?

A: The minimum period of purity is 15 days. This means that i there is bleeding after ten days, and before 15 days it will not be considered menses because the minimum period of purity has no passed. There is no maximum period of purity. If she does no menstruate for years, she will still be pure until she bleeds.
