Due Date by LMP

The estimated date of delivery EDD , also known as expected date of confinement [1] , and estimated due date or simply due date , is a term describing the estimated delivery date for a pregnant woman. Confinement is a traditional term referring to the period of pregnancy when an upper-class, noble, or royal woman would withdraw from society in medieval and tudor times be confined to their rooms with midwives, ladies-in-waiting and female family members only to attend them. Except in threatened pregnancies for example, in pre-eclampsia , “lying-in” or bedrest is no longer a part of antenatal care. According to American Congress of Obstetricians and Gynecologists , the main methods to calculate gestational age are: Childbirth on average occurs at a gestational age of days 40 weeks , which is therefore often used as a standard estimation for individual pregnancies. There is in any case considerable variation among individual pregnancies. Given that these gestation lengths are only estimates of an average, it is helpful to consider gestation time as a range of dates rather than as a single “due date”. The median is merely a guideline for the day at which half of all births occur earlier, and half of all births occur later. Births rarely occur on a due date, but they are clustered around due dates. Naegele’s rule is a standard way of calculating the due date for a pregnancy when assuming a gestational age of days at childbirth. The rule estimates the expected date of delivery EDD by adding a year, subtracting three months, and adding seven days to the origin of gestational age.

A podcast about pregnancy and drug use, Native people and tribal sovereignty. When people discuss how far along in pregnancy someone is, they tend to do so in general terms: Medical professionals use a standard set of up to three methods to date pregnancies: That way, regardless of where they trained or where they practice, any two doctors dating a pregnancy will predict the same due date or gestational age. However, the timing of the actual delivery is not so predictable. Some women will deliver on their due date, others before, and others after.

Join NursingCenter to get uninterrupted access to this Article. Accurate determination of the estimated due date EDD during pregnancy has personal and social significance for the woman and her family, guides obstetric evaluation and intervention, and has research and public health consequences. Ultrasound measurement of the crown-rump length CRL in the first trimester is considered the most accurate estimator of the EDD. Once the EDD is determined it should be documented in the medical record and discussed with the patient. Although determination of the EDD is a responsibility of the obstetric provider, nurses should be aware of the process of standards-based determination of EDD to give the most accurate and current information to women and their families and to enhance the nurse’s advocacy role surrounding gestational age-based assessments and interventions.
