EDD Calculation methods
The estimation of EDD is a process and there are many methods to calculate the estimated date of delivery. The estimated due date is calculated in two steps –
First, the time point to be used is determined as the origin for the estimated age. Here this estimated starting point is the woman’s last normal menstrual period (LMP) or the corresponding time that is estimated by a more accurate method. In these methods, the 14 days to a known duration from the time of fertilization is added.
The second step of EDD calculation is where the estimated age at childbirth is added to the above time period. Normally the childbirth happens at an estimated age of 280 days or 40 weeks. This is the time period of childbirth is generally used as a standard estimation for individual pregnancies.

If this gestational age calculated from an early ultrasound is not matching then still the ultrasound estimated age is used for the rest of pregnancy instead of the calculated age from the last menstrual period.
- If there in vitro fertilization then days from incubation is calculated by adding extra 14 days.
