Dating scans are usually recommended if there is doubt about the validity of the last menstrual period. By 6 to 7 weeks gestation the fetus is clearly seen on trans-vaginal ultrasound and the heart beat can be seen at this early stage 90 to beats per minute under 6 to 7 weeks, then to beats per minute as the baby matures.

Ultrasounds performed during the first 12 weeks of pregnancy are generally within 3 – 5 days of accuracy. The most accurate time is between 8 and 11 weeks gestation.

Many women with longer pregnancies find that everyone is asking whether they have had their baby yet, and that health care workers start to suggest inducing labour.

For some women this will be the right decision, but it is important to know that this is your decision to make. Charting temperature, monitoring mucus, using ovulation test kits and knowing times when you could have conceived, or having conceived by IVF may mean you have your own information about when you became pregnant. There is a tendency for midwives and doctors to talk as though the EDD written in your maternity notes is something definite, rather than an estimate which may or may not be accurate.

In that case, if the EDD is later than it should be that could mean that the birth is delayed unnecessarily. This suggests that in general ultrasound dating is more accurate in predicting the birth date than counting from the last monthly period 1,2 but it is still only an estimate and may not always be accurate. A recent study 3 of women who conceived by IVF and therefore knew when their egg was fertilised, found that the routine ultrasound dating scan consistently put their estimated birth date earlier than it should have been by an average of 3 days.
