Methods for Estimating the Due Date

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. Transvaginal ultrasound involves placing a thin transducer slightly thicker than a tampon into the vagina. The transvaginal ultrasound can offer extra detail to the examination as it allows the ultrasound probe to come into close proximity to the uterus womb.

Dating scans

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.

As long as the timings are right, you can have the NT scan and blood test at the same appointment.
