Menstral Cycle
Day 1 is the first day of bleeding. Last day is the day prior to the start of next period. Average cycle is 28 days with an average bleeding duration of 3-5 days.
For humans, 28 days on average with menstruation ending on day 1 and ovulation occurring on day 14. But, every woman's cycle is different. Talk with your gynecologist for more information.
Water cycle is a continuous process. It will last long.
