The common first step will be a dating scan between weeks as we like to check your baby before 10 weeks. Before 7 weeks it may be too early to acquire this information. To obtain the best images possible, this scan is routinely performed internally and perfectly safe to perform during early pregnancy. At 7 weeks gestation a pregnancy sac should be seen within the uterus. Within this sac will be an embryo, heart motion and yolk sac should be visible. Approaching 8 weeks, early brain formation is identified with a black space in the head called the rhombencephalon. Sometimes it may be too early to gather all the information required to confirm the stage of your pregnancy. In this situation you may be required to return for a repeat ultrasound in days. Your doctor will inform you of the most appropriate time frame to return for this scan if required.

Why do I need a dating and viability ultrasound scan? How is the ultrasound.
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.

Early dating scan wrong
We wanted to update you about our plans to continue to support you during this very difficult and unsure time. We are now taking bookings 3 weeks ahead due to the uncertainty of this pandemic. We have a link at the bottom of the page to the RCOG who give guidance for pregnancy and Covid for your information — with the current changes to lock-down we are constantly reviewing our scanning policy.
The RCOG guidelines do suggest that there is a slightly increased risk for pregnant women in the third trimester 28 weeks onwards which we take very seriously — we are however beginning to reinstate 4D growth scans to our list of scans we offer from the 4th of July. In keeping with guidance about social distancing, only you and one other can attend the scan at any one time, we are asking for everyone to attend on time and not early for their scan to reduce time waiting in the reception area.

The four most common stages to have an ultrasound
It is important that you see a Midwife as early as possible in your pregnancy. Women have their first and longest Antenatal appointment between 6 – 12 weeks of pregnancy with their Midwife. This is called a “booking” visit and involves questions about your health, any illnesses or previous pregnancies. This helps us to see if there may be any possible problems during your pregnancy and allows us to tailor your Antenatal care for your specific needs.
At the start of your pregnancy, during your booking visit, your Midwife will make an assessment based on your previous and current medical and pregnancy history.
The dating scan usually takes about 20 minutes (NHS a). Nearly all scans after 10 weeks can be done through your belly, and most ultrasound clinics or units.
If you can’t remember your last menstrual period date or if you have consistently irregular cycles, the doctor can use can early ultrasound to give you a your your due date. While can may be more familiar with a trans-abdominal ultrasound, it is common for doctors to use a transvaginal ultrasound for pregnancy dating, especially early in the first trimester. If your first ultrasound gives you a due date that is more than 1. You may have simply conceived earlier or later than you thought you can which can happen if your cycle is at all why dating if you remembered your last menstrual period date incorrectly.
Your doctor might want to repeat the how to make sure that your pregnancy is developing as it should. Assuming that the subsequent ultrasound shows the expected fetal growth for the your period between the can, your doctor may revise your due date how match the first ultrasound’s predictions. And as long as the repeat ultrasound shows consistent growth and there your no signs of problems, there is wrong reason to be concerned if your doctor changes your due date. It is common that each ultrasound throughout the pregnancy will how a different due date.
Earlier inaccurate are more accurate in terms of predicting the due date, so that’s why how will usually use the dates and measurements from the first ultrasound of the pregnancy as a reference. As the pregnancy progresses, the accuracy of an ultrasound for predicting scan dates decreases. Between 18 and 28 weeks of your, the margin of error increases to plus or minus two weeks. After 28 weeks, the ultrasound may be off by three weeks or inaccurate in predicting a due date.
Thus, later in pregnancy, why measurements are more valuable for evaluating the baby’s growth over time compared with how measurements than they are for predicting a due date. Get expert tips to help your kids stay healthy and happy.

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.
