How long will it take for my period to regulate once coming off the pilll I have been off the pill for more than 6 months and it seems my period gets later and later each month?

Your periods after you stop the pill are likely to resume the pattern they had before you were on the pill. Count the days for those six months from the first day of one period to the first day of another. If the number is between 24-35 days, you are well within the range of normal. If the number is outside that range, contact your health care provider. After six months, the pill is out of your system and is not affecting your menstrual cycle.
