The information should not be construed as dictating an exclusive course of treatment or procedure to be followed. As soon as data from the last menstrual period, the first accurate ultrasound examination, or both are obtained, the gestational age and the estimated due date EDD should be determined, discussed with the patient, and documented clearly in the medical record. Subsequent changes to the EDD should be reserved for rare circumstances, discussed with the patient, and documented clearly in the medical record. When determined from the methods outlined in this document for estimating the due date, gestational age at delivery represents the best obstetric estimate for the purpose of clinical care and should be recorded on the birth certificate.
Methods for Estimating the Due Date
It is common to be given a single ‘estimated due date’ EDD which corresponds the point at which it is estimated that your pregnancy will have lasted 40 weeks. It may be more helpful to be prepared for you baby arrive some time after 37 weeks, and to focus on 42 weeks as the time by which you have a good chance of having given birth.

Along with the emotional toll a miscarriage can take on couples, a major source of frustration is being left with a myriad of unanswered questions. Whilst this adds to the frustration it can also mean you are more likely to achieve a healthy pregnancy in the future.
Miscarriages can present in many ways, with some women experiencing a period like pain and bleeding. For others, there may be no symptoms and the miscarriage is picked up incidentally on a routine ultrasound. In some cases, an ultrasound can pick up features that the pregnancy may not be optimal and further testing or follow-up may be required by their fertility specialist.
To confirm a viable pregnancy an early dating scan is recommended. If this is confirmed, then the chance of a miscarriage occurring is greatly reduced. As miscarriages are common, it is not unexpected that other family members may have suffered one or more miscarriages.

Document findings as per Early pregnancy ultrasound examination see above :. Once a live embryo is visible, the CRL should be used to calculate the due date. The MSD should not be included in this calculation. For reporting pro forma examples, see First trimester reporting pro forma. Skip to main content. First-trimester ultrasound.

Most early pregnancy scans less than 7 weeks will require transabdominal TA and transvaginal TV imaging. TA imaging alone may be sufficient if excellent visualisation of a live intrauterine embryo is achieved and the woman is asymptomatic. TV imaging should always be offered when the indication includes abnormal symptoms, such as bleeding or pain.
