What to expect at your 6-week ultrasound appointment

A first trimester early pregnancy and dating ultrasound is an examination you have during the first 13 weeks of pregnancy. Due to the size of the developing structures and embryo, it is uncommon to perform an ultrasound before 5 weeks gestation 5 weeks after the start of your last menstrual period. Ultrasound is not consistently able to confirm viability and fetal heart activity prior to 6 weeks gestation, so unless there is an urgent need to have an early pregnancy and dating scan earlier most of these ultrasounds are performed after 6 weeks and ideally at 8 weeks for dating purposes.

Urgent cases may still be performed earlier, please discuss this with your referring doctor. Your ultrasound may be performed transabdominally or transvaginally.

Today’s obstetrician gynecologist is required to interpret and in many cases perform ultrasound scans in the first trimester. In fact, certification of residency programs in many countries requires documentation of adequate exposure to and training in the evaluation of first-trimester ultrasound. Failure to understand the limitations of diagnostic ultrasound or inadequate training of physicians in this technique can result in grave complications for the patient and liability for health-care providers.

The standard of care for performing routine ultrasound examination at 6—7 weeks varies from country to country. The disadvantages of performing this examination routinely are related to cost, errors in diagnosing ectopic pregnancies that in fact are intrauterine, increased training requirements for providers, and potential biologic hazards to the fetus that are presently unknown.

Ultrasound scans use sound waves to create a picture of the baby in the womb. Most women have one or more ultrasound scans during pregnancy. The two scans routinely offered during pregnancy are the nuchal scan and the anatomy scan. Sometimes other scans are performed earlier or later in pregnancy to check the growth of the baby, the position of the baby or the placenta, or for other reasons. A baby and heartbeat can be seen on the scan after 6 weeks.

This measurement, known as the crown rump length (CRL), is very accurate in the first trimester (Butt and Lim , Van Hof et al ). How big your baby will be.

An ultrasound is a highly accurate means of dating a pregnancy. In a normal pregnancy, ultrasound can provide an estimate of the gestational age to within five to seven days of accuracy. In the first trimester, doctors usually use a transvaginal rather than abdominal ultrasound. The transvaginal ultrasound provides the most accurate information, given that the early developing gestational sac and fetal pole are extremely tiny at this point.

A transvaginal ultrasound can get closer to the developing pregnancy. In a transvaginal ultrasound, the doctor or technician inserts a thin probe into the vagina. During the ultrasound, they take a series of measurements, including the size of the gestational sac, the size of the yolk sac, the length of the fetal pole, and the heart rate. In an abdominal ultrasound, the woman will be asked to come to the scan with a full bladder, because this positions the uterus in a way that makes it easier to obtain measurements.
