Dating Scan / 12 Week Scan: What Should You Expect?
The dating scan, also known as the 12-week scan, is one of the most significant milestones in early pregnancy. It provides valuable information about the health and development of your baby, and for many, it’s the first time you’ll see your baby. Here’s what you need to know about what to expect from a dating scan.
What is a Dating Scan?
A dating scan is an ultrasound scan performed between 10 and 14 weeks of pregnancy. It is primarily used to establish the gestational age of the pregnancy and to provide an estimated due date (EDD). The scan can also detect multiple pregnancies (e.g., twins or triplets) and check the baby’s development and heartbeat.
Why is a Dating Scan Important?
Establishing Gestational Age
One of the main purposes of the dating scan is to determine how far along the pregnancy is. This is done by measuring the size of the fetus, particularly the crown-rump length (CRL). Accurate dating is crucial for monitoring the baby’s growth and development throughout the pregnancy.
Detecting Multiple Pregnancies
The scan can reveal if you are carrying more than one baby. Identifying multiple pregnancies early allows for appropriate monitoring and management throughout the pregnancy.
Checking for Viability
The scan checks for the baby’s heartbeat and overall development, providing reassurance that the pregnancy is progressing normally.
Assessing the Risk of Chromosomal Abnormalities
The dating scan can also include a nuchal translucency (NT) measurement, which assesses the risk of chromosomal abnormalities such as Down syndrome. This is usually done in combination with a blood test.
Preparing for the Dating Scan
Booking the Scan
Your healthcare provider will usually arrange the dating scan as part of your routine prenatal care. It is typically scheduled between 10 and 14 weeks of pregnancy.
Hydration
You may be advised to drink water before the scan to fill your bladder, which can help provide clearer images. A full bladder pushes the uterus into a better position for the ultrasound.
What to Wear
Wear comfortable, loose-fitting clothing. You might need to partially undress or lift your top to expose your abdomen for the scan.
During the Scan
The Procedure
- Positioning: You will lie on an examination table, and a clear gel will be applied to your abdomen to help conduct the sound waves.
- Transducer: The ultrasound technician will move a handheld device called a transducer over your abdomen. The transducer sends out sound waves that bounce off the baby and create images on a monitor.
- Images and Measurements: The technician will capture images and measure the baby’s size, including the crown-rump length (CRL). The presence of the heartbeat will also be confirmed.
What You Will See
During the scan, you’ll be able to see your baby on the monitor. At 12 weeks, you can often see the baby’s head, body, and limbs. The technician will point out different parts of the baby’s anatomy and explain what you are seeing.
Duration
The scan typically takes about 20 minutes. However, it might take longer if the baby is in a position that makes it difficult to get clear images or measurements.
After the Scan
Results
The results of the dating scan are usually discussed with you immediately after the procedure. The technician or your healthcare provider will explain the findings, including the estimated due date and any observations about the baby’s development.
Next Steps
If any abnormalities or concerns are detected, your healthcare provider will discuss further testing or follow-up scans. Most dating scans confirm that the pregnancy is progressing normally, providing reassurance for expectant parents.
Photos and Videos
Many clinics offer printed photos or digital copies of the scan images. These can be a cherished keepsake of this early stage of pregnancy.
The dating scan, or 12-week scan, is an essential part of prenatal care, providing critical information about the gestational age and health of your baby. Understanding what to expect can help you prepare for the scan and make the experience more enjoyable and less stressful.
