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.

Many important developmental problems can be seen with a scan at this stage. Placenta previa where the placenta is covering the cervix can be diagnosed during the anatomy scan, but as the baby develops and the uterus gets bigger, the placenta usually moves away from the cervix.
It is usually not possible to know if the placenta has moved far enough for a normal birth until 32 weeks and sometimes even later.

It is common to be given a single ‘estimated due date’ EDD which corresponds the point at which it is estimated that your pregnancy will have lasted 40 weeks. It may be more helpful to be prepared for you baby arrive some time after 37 weeks, and to focus on 42 weeks as the time by which you have a good chance of having given birth.
Many women with longer pregnancies find that everyone is asking whether they have had their baby yet, and that health care workers start to suggest inducing labour. For some women this will be the right decision, but it is important to know that this is your decision to make. Charting temperature, monitoring mucus, using ovulation test kits and knowing times when you could have conceived, or having conceived by IVF may mean you have your own information about when you became pregnant.
There is a tendency for midwives and doctors to talk as though the EDD written in your maternity notes is something definite, rather than an estimate which may or may not be accurate. In that case, if the EDD is later than it should be that could mean that the birth is delayed unnecessarily. This suggests that in general ultrasound dating is more accurate in predicting the birth date than counting from the last monthly period 1,2 but it is still only an estimate and may not always be accurate.
A recent study 3 of women who conceived by IVF and therefore knew when their egg was fertilised, found that the routine ultrasound dating scan consistently put their estimated birth date earlier than it should have been by an average of 3 days.

The scan may also show if you are expecting a baby girl or boy. The hospital will not offer you another scan if this is the case. The person performing the scan is called a sonographer. The sonographer will put gel onto your tummy to start the examination. The gel usually feels cold and you may feel a little discomfort when the ultrasound probe transducer presses on your tummy. An ultrasound scan takes approximately 10 minutes to complete. A screen will be visible for you to also see what the sonographer is looking at.
It is advised you have a full bladder, when having a scan. This helps the ultrasound echoes to reach your womb, giving them a better view of your baby. The transducer sends high frequency sound waves in your abdomen to build a picture of the baby. These waves bounce off your baby and back to the computer to be translated into a picture. Hard tissues, such as bone, reflect the most sound waves and make the biggest echoes. These appear white in the image, and soft tissues appear grey.
Should a first trimester dating scan be routine for all pregnancies?
Dating a pregnancy accurately at the earliest possible time is important. In a normal pregnancy it does not matter what the dates are, but if anything should go wrong it becomes very important as to what treatments may be prescribed. Traditionally the last menstrual period has been used to date a pregnancy, but this may be highly inaccurate.
A simple formula is to take the first day of the menstrual period, subtract three months and add one week. For instance, if your period starts on the 5th April, then your estimated due date for delivery is the 12th January. The dating scan is an ultrasound scan that can be done as early as six weeks after the last period, but the dating scan will be most accurate when done between 8 and 12 weeks gestation.
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.
A transvaginal scan is optional for all patients and it is your decision whether to proceed with that part of the examination. Ultrasound, both transabdominal and transvaginal, is considered to be safe during the first trimester of pregnancy.
