What is your menstrual cycle?

Your menstrual cycle is the time from the first day of your period to the first day of your next period. Your menstrual flow on the other hand usually lasts 3 to 7 days, but it may be slightly shorter or longer while a normal menstrual cycle can be as short as 21 days or longer than 35 days. For the majority of women, their menstrual cycle is between 25-30 days long, but it’s not unusual for the number of days in each cycle to vary from month to month.
