What is Normal Menstruation Frequency?
Between the dates when menstruation begins, there must be at least 21 days and at most 35 days. Not every woman needs to have menstruation every 28 or 30 days, with 21-35 days being considered normal. When counting this period, it is necessary to count the time from the first day of one menstruation to the first day of the other menstruation. It is not correct to count the days between cleanings.
