Question
Hello Rabbi, should a woman with a regular cycle be concerned about her cycle on the thirtieth day?
Answer
Shalom and blessings.
The sages have stated that most women typically see on the thirtieth day after their last cycle, and therefore it is obligatory to separate at this time, which is called 'average period'.
However, regarding a woman with a regular cycle, there is a distinction. If the regular cycle is longer than thirty days, such as seeing on the 33rd day after her last cycle, she does not need to be concerned about the average period. But if the regular cycle is shorter than thirty days, and she did not see during her regular cycle, she should be concerned about the average period. (In such a case, she only needs to be concerned about the thirtieth day itself during the period when she last saw, and not about other periods that are usually added and concerned about in a regular manner).
