Question

What is the criterion for changing or losing a woman's menstrual habit? [AR_ID:1641]

Answer 1

Peace be upon you.

Grand Ayatollah Sayyid Sistani (may Allah protect him):

1- A menstrual habit does not change with the sighting of blood once, contrary to the previous habit.

2- If a woman sees blood twice in a similar manner contrary to her first habit, her habit changes to the second.

3- If she sees blood twice contrary to her first habit but in different manners, she is considered irregular.

4- If she sees blood many times contrary to her first habit in different ways, her habit is nullified and she is considered irregular.

5- A habit is nullified if blood is seen for two consecutive months for more than ten days.

6- A habit is nullified if blood is seen for more than two months, exceeding ten days each month.
