What has happened before my 20-week pregnancy check?
Before your 20-week scan, your GP or health care clinic would have organised some blood tests and a scan to check your baby’s risk of having a genetic abnormality. If your baby had a low chance, your next scan would be when you are between 18 and 20 weeks pregnant.
What will happen when I’m 20 weeks pregnant?
When you are between 18 and 20 weeks pregnant, your GP or midwife will organise a scan with an ultrasound specialist. The ultrasound will be performed by placing a probe onto your belly and moving it around on top of some gel so they can get a good look at baby. In some cases, they may also put an internal scanner in your vagina to check the length of your cervix.
Why am I doing this scan?
This scan checks your baby is growing well, is moving around correctly, and your placenta is sitting in a good spot in your womb. They can also use the ultrasound to check your baby’s inside to make sure baby is growing well, and everything looks good.
