Gestational age is a measure of the age of a pregnancy which is taken from the beginning of the woman's last menstrual period LMP , or the corresponding age of the gestation as estimated by a more accurate method if available. Such methods include adding 14 days to a known duration since fertilization as is possible in in vitro fertilization , or by obstetric ultrasonography. The popularity of using such a definition of gestational age is that menstrual periods are essentially always noticed, while there is usually a lack of a convenient way to discern when fertilization occurred. The initiation of pregnancy for the calculation of gestational age can be different from definitions of initiation of pregnancy in context of the abortion debate or beginning of human personhood. According to American Congress of Obstetricians and Gynecologists , the main methods to calculate gestational age are: [1].

When LMP and Ultrasound Dates Don’t Match: When to Redate?

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 and 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: [6]. 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.

Estimated date of delivery

The due date, also known as the estimated date of confinement, is an estimation of when a pregnant woman will deliver her baby. Due dates can be estimated using a number of different methods including last menstrual period, ultrasound, conception date, and IVF transfer date. The default for this calculator bases the calculation on a woman's last menstrual period LMP , under the assumption that childbirth on average occurs at a gestational age age of a pregnancy calculated from the woman's last menstrual period of days, or 40 weeks. Although there is some debate regarding when pregnancy technically begins, whether at fertilization of the egg conception , or when the egg adheres to the uterus implantation , gestational age does not vary based on different definitions of pregnancy since it is based on LMP.

Due Date by LMP

Because the human egg is capable of fertilization for only 12 to 24 hours after ovulation the date of ovulation may be taken as being the date of conception. However, ultrasound determination of the date of ovulation has the same imprecision as does the ultrasound estimate of the gestational age and, therefore, a precise date of conception cannot usually be determined as with in vitro fertilization. In addition, although a woman is most likely to become pregnant if she has sex on the day of ovulation conception may also occur from live sperm still in her reproductive tract on the day of ovulation if she had sex for up to five days before ovulation [26,27]. The due date may be estimated by adding days 9 months and 7 days to the first day of the last menstrual period LMP.
