Scan at 18-20 weeks Bookmark this page

You can have this ultrasound scan at 18-20 weeks of pregnancy to check that your baby is growing normally and to check the position of your placenta.

This detailed ultrasound looks at your baby’s body parts and picks up any obvious problems in development or growth, like spina bifida, heart defects and limb defects. If you want to find out the sex of your baby, this is the time to ask. You’ll probably see your baby’s heart beating, the curve of baby’s spine, baby’s face, and baby’s arms waving and legs kicking.

Your health professional will send you to a private clinic or public hospital department for the scan. The results will be sent to your health professional and possibly to you (if you’re having a homebirth).

This means you’re likely to need to see your health professionals more often and have more checks during pregnancy. Read more about health problems in pregnancy.
