The first trimester can be an exciting but anxious time. Expectant parents often need to wait for up to 15 weeks before they get their public maternity hospital appointment and the reassurance that everything is fine with their baby. With our private ultrasound scans, you can get this reassurance as soon as 8 weeks gestation so you can begin to enjoy your pregnancy with peace of mind. Pregnancy Scans performed during the first 12 weeks of pregnancy are generally within 3 — 5 days of accuracy. The most accurate time for the due date calculation is between 8 and 11 weeks pregnant. This is because your baby is growing so quickly that there is a big difference in size from week to week. Also, the baby cannot bend and twist very much yet, so the length of the body is fairly constant. However, the accuracy of the ultrasound examination is always dependent on the position of organs and internal bodily fluids.

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.

At 5 weeks into pregnancy things are so small there is very little to see on ultrasound. Even at 6 weeks it can be difficult to see an embryo with some people. We say 5 weeks plus because without being able to measure the embryo, we can only measure the mean sac diameter which is a combination of 3 measurements of the sac to gather an approximate date, but it isn’t as accurate and measuring the embryo.

At this point we can see the dark area with a small circle inside. The dark area is the gestation sac and the small white circle is called a yolk sac. The job of the yolk sac is to provide the growing embryo with nutrients until the placenta takes over later on into pregnancy.

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.

Whilst you may get a positive pregnancy test before your period is even due it is a couple of weeks before the pregnancy is big enough to be seen on scan. In the early weeks how much we can see in very early pregnancy is different for every woman and every pregnancy. At 4 weeks gestation 2 weeks after conception when you have just missed your period we cannot detect the pregnancy on scan, all we can see is that the lining of the womb has become thicker.

Somewhere between 4 and 5 weeks, we can sometimes see a small black fluid area in the uterus but we cannot confirm it is a pregnancy sac until we can see something growing inside it. During the 5th week we can usually see a small pregnancy sac around 6mm and within it we can usually see a yolk sac. This confirms to us that this is definitely a pregnancy sac.
