A first trimester early pregnancy and dating ultrasound is an examination you have during the first 13 weeks of pregnancy. Due to the size of the developing structures and embryo, it is uncommon to perform an ultrasound before 5 weeks gestation 5 weeks after the start of your last menstrual period. Ultrasound is not consistently able to confirm viability and fetal heart activity prior to 6 weeks gestation, so unless there is an urgent need to have an early pregnancy and dating scan earlier most of these ultrasounds are performed after 6 weeks and ideally at 8 weeks for dating purposes.
Urgent cases may still be performed earlier, please discuss this with your referring doctor. Your ultrasound may be performed transabdominally or transvaginally.
How long will the scan take? week scans normally take between 15 and 30 minutes. But it might take.
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. If you decide to go ahead with this optional screening test you will be offered a scan between 12 weeks and 13 weeks 6 days ideally 12 weeks. This is the only time that this scan can be performed. We send these measurements to LabPlus in Auckland where a blood sample from you is also sent. LabPlus then calculate the risk or chance that your pregnancy is affected with Down Syndrome.
Because this calculation is not carried out on site we are not able to give you the results straight away on the day. LabPlus will contact your midwife with the results and she will discuss the results with you. This is a detailed ultrasound scan, usually carried out when you are 20 weeks pregnant. So whilst a normal 20 week scan is very reassuring it cannot guarantee a healthy baby.
