The dating scan and anomaly scan are offered to all women, but you don't have to accept them.
This is because most babies are healthy and do not have abnormalities. If a problem is found or suspected, the sonographer may ask for a second opinion from another member of staff.
You might be offered another test to find out for certain if there is a problem.
Some women may be offered more than two scans, depending on their health and their pregnancy.
You can find out more about the dating scan and the anomaly or mid-pregnancy scan. Some people want to find out if their baby has problems, while others don't.
Talk to your midwife, GP or obstetrician about any concerns you have.
For many women, ultrasound scans are the highlight of pregnancy.Please ask your hospital about this before your appointment.Remember, an ultrasound scan is an important medical examination and it is treated in the same way as any other hospital investigation.A black and white picture of the baby will appear on the ultrasound screen.During the examination, sonographers need to keep the screen in a position that gives them a good view of the baby.You'll be given the chance to discuss it with your maternity team before making your decision. You may like someone to come with you to the scan appointment.
