What your baby scans will tell you

Here’s a guide to the pregnancy scans you’ll be having: what they mean, and when they happen.

    At a glance

    Your first pregnancy ultrasound can happen between 8 and 14 weeks and is also known as the dating scan.

    You can hear your baby’s tiny heartbeat at the first pregnancy scan. Don’t forget the tissues.

     

    The anomaly scan between 18 and 21 weeks is when you can find out the sex. Girl? Boy? Surprise?

    Every woman is offered a test for the risk of Down’s Syndrome. It’s up to you if you take it.

    Your scan is the first time you’ll see baby (wow) and the first time you get the thumbs up on a healthy pregnancy (gulp). You may well be full of mixed emotions, so having your partner or friend to share the moment could be a good idea.

    The 12 week scan

    For most mums the 12 week scan will be their first baby scan and it can happen anytime between 8 and 14 weeks and is also known as the dating scan. It will give you a more accurate idea of when baby is due, usually it’s not as far advanced as the date of your last period suggests.

    Your sonographer will check that the heart is beating nicely and baby is growing normally. The position of the umbilical cord will be visible and any major issues with the skull or abdominal wall could be spotted now.

    Down Syndrome Screening

    At your dating scan you’re likely to be offered a combined test to assess your chances of having a baby with Down’s Syndrome. If you choose to have it, a blood sample will be taken, and the nuchal translucency will be measured. In plain English, this is the thickness of the fluid in the back of baby’s neck – babies with abnormalities tend to have more fluid.

    The results of the two tests combined with your age (older women are at higher risk) are used to come up with a risk factor for having a baby with Down’s Syndrome. It also tests for Edward’s and Patau’s, which are rarer but more severe conditions.

    Many women choose to have the combined test, but the choice is yours and it’s worth thinking about your decision.

    The 18-21 weeks anomaly scan

    Your second scan will be around 18-21 weeks. It’s called an anomaly scan and it checks that your baby and their organs are growing normally. The sonographer will also measure the amniotic fluid around your baby and check the position of your placenta – if it’s lying low, it could obstruct the passage of the baby in labour so a caesarean might be a consideration. It’s possible that another scan could be scheduled to check if the placenta has risen in time.

    You’ll be offered just these two scans as routine and you’ll have the option to take a picture of your ‘jellybean’ home with you. Most likely, the next time you see baby will be in your arms.
