What is ‘Adjusted Cycle Length’?

I would like to know what adjused cycle length means Thank YOU!”

Thank you for writing! “Adjusted cycle length” means that whomever calculated your due date has taken into account more factors than the date of your last menstrual period (LMP) so that your estimated due date (EDD) will be more accurate.

Unless measurements taken by ultrasound have been used to determine the age of a fetus, pregnancy due dates are traditionally established by adding a year, then subtracting three months, then adding seven days to the first day of your last period. But this method can be off by more than a week, because it’s based on some assumptions that may not be true, among them that every woman has a 28-day cycle. In reality, very few women have a 28-day cycle; anything between 21 and 35 days is normal. So an adjusted cycle length takes this into account: if your cycle is shorter than 28 days, then days will be subtracted from your due date. If your cycle is longer, days are added.
