As you reach the 12-week mark of your pregnancy journey, you’re about to embark on a significant milestone: your 12-week pregnancy scan. Also known as the dating scan or the first trimester screening, this ultrasound examination offers a wealth of information about your baby’s development and well-being. So what can you expect from your 12 week scan? Here we delve into every aspect, from its purpose and process to what to expect during the appointment and beyond.
What is the 12 week scan looking for?
Understanding the Purpose: Often the first pregnancy scan, the 12 week scan serves several crucial purposes. Primarily, it’s known as the dating scan because it helps confirm your due date, providing you with a clearer timeline for your pregnancy journey. Additionally, this scan is part of the first trimester screening tests, which aim to assess your baby’s growth and detect any potential issues early on.
Why do I need a 12 week scan?
Delving into the Process: During the 12-week ultrasound scan, high frequency sound waves are used to create detailed images of your baby in the womb. These sound waves are harmless and provide invaluable insights into your baby’s development, allowing your healthcare provider to assess various aspects such as fetal size, heartbeat, and organ formation.
The scan usually takes around 15 minutes to complete and the sonographer will usually let you know that all is looking well before you leave the appointment. Occasionally, you may need to be referred to see a consultant or midwife on the day, especially if any abnormalities or points for concern are found.
Are there any other tests at the 12 week scan appointment?
Understanding Nuchal Translucency and Syndrome Screening: A crucial component of the dating scan is the measurement of nuchal translucency (NT), which refers to the fluid-filled space at the back of your baby’s neck. Abnormalities in the NT measurement can indicate an increased risk of certain genetic conditions. Combined with other factors such as maternal age, the results of these screening tests help determine your baby’s overall risk of chromosomal abnormalities.

How do I know that my baby is well?
Aside from this, the ultrasound technician is usually happy to share their findings and show you images on the screen of your baby. You can ask questions, but sometimes the answers are best heard from a consultant after the scan, so don’t worry if you’re told to wait.
What should I do before a pregnancy scan?
Preparation and Practical Tips: Before your 12-week pregnancy scan, your healthcare provider may advise you to have a full bladder, as this can help enhance the clarity of the ultrasound images. You can do this by drinking around a pint or 500mls of water approximately 1 hour before your appointment. Try to resist the urge to go to the toilet before your scan. You can usually check with the receptionist to find out if the clinic is running to time.
You may also want to wear clothing that is easy to pull up, for example leggings and a dress or long top can feel more comfortable to slide up and roll down, so the sonographer has access to the entire area they’ll need. This isn’t the time for dungarees or jumpsuits! The sonographer will apply a cold gel to your growing bump to allow the probe to move more freely over your skin. You’ll usually be required to wipe this gel away afterwards with some paper towels provided.
Additionally, don’t hesitate to ask questions and seek clarification about the scan process or any concerns you may have.
How will I feel after my 12 week scan?
Emotional Support and Antenatal Care: The 12-week pregnancy scan can evoke a range of emotions, from excitement and anticipation to anxiety and apprehension. It’s essential to acknowledge and address these feelings, both individually and with your partner or family members. Lean on your support network and healthcare team for support during this time if needed.
Additionally, prioritise your mental health and well-being by seeking out resources such as counselling services or support groups if needed. For some, the 12 week scan is a time of excitement, anticipation and joy. But for others, particularly those who have experienced loss, fertility issues or postnatal mental health issues with previous babies, it can be nerve wracking and anxiety inducing. Rest assured that the sonographer will have experience of supporting parents-to-be through this difficult time.
What should I do after my pregnancy scan?
Celebrating Your Journey: The 12 week pregnancy scan is a pivotal moment in your pregnancy journey, offering invaluable insights into your baby’s development and overall health. Remember, each scan is a unique opportunity to connect with your growing baby. For partners, it’s a chance to have a ‘window’ into the womb and ask questions they may have about the baby’s development too.
If you have any concerns about your pregnancy, remember to speak with your midwife. At this stage, you may not have met your community midwife or care team. If you don’t yet have numbers to call, speak to your GP to ensure you get the answers you need without delay. This might be the time to research your options about where to give birth or whether getting support from a private midwife might be for you.
