Five dating methods: LMP, FH, US and their combinations, were assessed against the actual day of delivery (ADD).The main outcome measures were: (i) the days between the ADD and estimated date of delivery in pregnancies where spontaneous labour occurred and the baby had a normal birth weight; (ii) the incidence of gestational age-related outcomes; and (iii) the influence of clinical variables on dating discrepancies. The accuracy of dating was similar for certain and uncertain LMP. US-based dating was most accurate (for 85% of predictions within 14 days) and similarly accurate at 20 - 24 weeks and at Pregnancy dating by US, including those in more advanced pregnancies than currently permitted, is recommended since all non-ultrasound-based estimations of gestational age were considerably less accurate.Optimal management of pregnancy relies on accurate assessment of the gestational age (GA) of the fetus; which can be determined by the history of the last menstrual period (LMP), clinical estimation of the 1st symphysis-to-fundal height measurement (FH) or ultrasonographic fetal biometry.However, many women fail to recall their LMP accurately.1 Moreover, pregnancy duration and fertile period are highly variable, even for women with regular cycles.1 FH suffers from poor reproducibility and high variability due to maternal and fetal factors;2-4 its accuracy for dating has not been extensively studied5-7 and requires FH dating charts (rather than growth charts).Pregnancy ultrasounds are performed mainly using transabdominal ultrasound.

The transvaginal ultrasound probe is thin, about 2cm diameter.

The accurate determination of a patient's "due" date, referred to by doctors and midwives as the EDC (Estimated Date of Confinement) or EDD (Estimated Date of Delivery), is very important for a variety of reasons.

With today's modern equipment, we can obtain very reliable images and measurements of even very early pregnancies, sometimes even seeing a heartbeat as early as 5-6 weeks!

The most common misconception we encounter almost daily, has to do with how accurate ultrasounds are in fixing the EDC at different stages of pregnancy.
