The average menstrual cycle is 28 days long. However, a normal cycle can be shorter or longer than this. It may be anywhere from 21 to 35 days long. Most periods last 3 to 5 days, but anywhere from 2 to 7 days is normal.
It's normal to have an irregular cycle or two now and then. But if you continue to have irregular periods, or if you don't have a period at all for three to six months, it's time to see your doctor. Most menstrual cycle intervals occur about every four weeks, with the normal range between 21 and 35 days. To calculate your menstrual cycle, start counting from the first day of your last period and stop counting on the first day of your next period.
