A dating scan might be recommended before 12 weeks to confirm your due date if you are unsure of your last menstrual period or your date of conception. The scan is optional and not everyone will have it. You can discuss whether you want or need a dating scan with your doctor or midwife.

Most women can instead have their first scan at 11 to 13 weeks — this is usually called the week 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.
