Unless there are concerns about the pregnancy it is better to wait to have this scan after 7 weeks as the images are clearer for you to see and better for us to measure. If you come before 7 weeks the baby will be less than 1cm in size and so the scan sometimes has to be performed transvaginally placing the probe inside the vagina to enable us to see the baby well enough to measure and to see the heartbeat. We ask that you come with a full bladder for this scan as it usually allows us to get the best possible picture of the baby.

A dating scan is an ultrasound examination which is performed in order to establish the gestational age of the pregnancy. Most dating scans are done with a trans-abdominal transducer and a fullish bladder. If the pregnancy is very early the gestation sac and fetus will not be big enough to see, so the transvaginal approach will give better pictures.
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.
This is because the fetus is growing so quickly that there is a big difference in size from week to week. However, the accuracy of the ultrasound examination is always dependent on the skill of the sonographer and the quality of the equipment. The EDD from the early dating scan is used – if the last menstrual period is not known or is unreliable, or the dating scan differs from the last menstrual period dating by more than 5 days.
Ultrasound examinations from 12 to 22 weeks are regarded as being within 10 days of accuracy or up to 10 days earlier or 10 days later than the woman’s calculated due date.
