If you choose to have a dating scan, it will most probably be your first scan. You will need to get a referral from your doctor or midwife for a dating scan.
Your 12-week pregnancy dating scan
A dating scan is carried out by ultrasound. A sonographer, who is usually a radiographer or a midwife trained in ultrasound, will complete your scan. If the scan is after 10 weeks, ultrasound recordings are usually made through your abdomen. The sonographer will put gel on your abdomen and move a hand-held device called a transducer, back and forward over your skin.
In some situations, such as when the scan is completed before 10 weeks of gestation or you are overweight, you may also need a vaginal scan. Your sonographer will let you know if this is needed. For an abdominal dating ultrasound, you will need to have a full bladder.
You may be asked to drink some water and not go to the toilet beforehand because a full bladder helps to push your womb up to give a better picture.
