What is the average cycle length?

The menstrual cycle, which is counted from the first day of one period to the first day of the next, isn't the same for every woman. Menstrual flow might occur every 21 to 35 days and last two to seven days. For the first few years after menstruation begins, long cycles are common.

Regarding this, how do I calculate my period cycle length?

To calculate menstrual cycle length, you count the number of days from day one of your period (CD 1) up to, and including, the day before the next period starts. The count does not include the first day of the next menstrual period, because that's Cycle Day 1 of the next cycle.

How do you count the days of your cycle?

The answer is the date of the first day of your last period (not the day it ended). Ex.= February 2nd. To figure out how long your cycle is, start at cycle day 1 of your last menstrual cycle and begin counting (Cycle day 1,2,3,4 and so forth). The length= the last cycle day before you started bleeding again.

How long does an average period last?

On an average a period lasts between 3 to 5 days. It is normal for a girl to have irregular periods in the beginning. During this time, the duration of her periods may vary from as short as 2 days to as long as 7 days. It can take up to a year for periods to become regular.
