A dating scan is an ultrasound examination which is performed in order to establish the gestational age of the pregnancy. Most dating scans are done with a trans-abdominal transducer and a fullish bladder. If the pregnancy is very early the gestation sac and fetus will not be big enough to see, so the transvaginal approach will give better pictures. Dating scans are usually recommended if there is doubt about the validity of the last menstrual period. By 6 to 7 weeks gestation the fetus is clearly seen on trans-vaginal ultrasound and the heart beat can be seen at this early stage 90 to beats per minute under 6 to 7 weeks, then to beats per minute as the baby matures. Ultrasounds performed during the first 12 weeks of pregnancy are generally within 3 – 5 days of accuracy. The most accurate time is between 8 and 11 weeks gestation.

A dating scan is an ultrasound scan to determine how many weeks pregnant you are and your due date. Read on for more information about what a dating scan offers. 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. 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. 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.

A pregnancy is based on being days long, which is 40 weeks more like 10 months not 9! When we give you a due date we consider 37 to 42 weeks to be full-term, so even if your baby is born two weeks before your due date it is not considered premature.
Because few women know the exact day they ovulated or conceived, an ultrasound done in the first trimester of pregnancy has been shown to the be the most accurate way to date a pregnancy. If an ultrasound date in the first trimester differs from your LMP date by seven days or more, we would go with the ultrasound. Ultrasounds done later in the pregnancy are less accurate for dating, so if your due date is set in the first trimester, it shouldn’t be changed.
However, if you did not get a first trimester ultrasound for dating and an ultrasound done to look at the baby’s anatomy usually at weeks of pregnancy differs from your LMP date by 10 to 14 days, we would change your date to the ultrasound estimate.
