Baby scans and pregnancy ultrasounds
Your first pregnancy scan can be an exciting yet nerve-wracking experience. It offers the first tangible signs of what’s going on inside and it’s the closest you’ll come to meeting your baby until they’re delivered into your arms. Learn about why scans are offered, and what to expect during a typical ultrasound scan.
What is an ultrasound scan?
An ultrasound scan bounces sound waves back and forth to build up a simple black and white picture of your baby as it grows in the womb. It’s a painless procedure with no known side-effects for mum or baby.
Your routine pregnancy scans
As part of the HSE pregnancy care program you will be offered two scans during your pregnancy. The first scan, also known as the dating scan, will take place before your 15th week of pregnancy, (typically around 12 weeks). The second pregnancy scan, also known as the fetal anatomy or anomaly scan will take place anytime between your 18th and 22nd week.

Early pregnancy scan
If you are experiencing pain or bleeding, have had a previous miscarriage or an ectopic pregnancy, you may be invited to have an early scan between six and ten weeks. This is not the same as an ultrasound scan as your baby will be very small at this stage. During this scan a probe will be inserted into your vagina to gain a clearer picture of developments and identify a heartbeat. Although more invasive than an ultrasound, it is a simple and pain-free procedure. Your medical team will be on hand to give you plenty of support and reassurance throughout.
You may be invited to have a third ‘growth’ scan around 32 weeks. This scan is not required for all pregnancies, but it is sometimes offered as a precaution to check your baby’s growth and position in the final few weeks.
