Dating scan pregnancy
The probe sends out ultrasound waves – sound waves with a frequency higher than the human ear is able to hear – to produce images of your baby, which the sonographer studies on a screen.Ultrasound scans in pregnancy have several purposes: Ultrasound scans have been used for many years, and there are no known risks to you or your baby from having the routine scans offered in pregnancy.Sonographers can usually tell you the sex of your baby at your NHS anomaly scan at around 20 weeks.However, sometimes it’s not possible to tell the sex at that scan as your baby might be in a position that makes it difficult for the sonographer to see, in which case you may want to have a private scan to check the sex later on.It takes up to two weeks to get the results, but you should be told within three working days if your baby is at high risk.
As well as the routine NHS scans, there are several different types of private scan that you might consider.
The advice from the National Institute for Health and Clinical Excellence (NICE) is to have your early scan and then the anomaly scan at 18-20 weeks.
Feeling anxious about your baby is quite natural during the early stages of your pregnancy and if you have any concerns you should consult your midwife first.
But for most women having straightforward, healthy pregnancies, the early pregnancy scan and the anomaly scan are all that are recommended.
Taking place between 8 and 14 weeks, the early pregnancy scan, or dating scan, is your first pregnancy scan.
