8 Week Ultrasound
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.
Your first pregnancy ultrasound can happen between 8 and 14 weeks and is It will give you a more accurate idea of when baby is due, usually it’s not as far.
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.
In any case, ultrasound does not give a very accurate prediction of the actual birth date.
How accurate is your baby’s due date? What to know about when you’ll go into labor
Throughout your pregnancy, we will conduct regular ultrasound examinations. We will also monitor the physical contours and organ structure. Make an appointment for an sneek peek ultrasound here. During your pregnancy, you will receive a minimum of 8 ultrasounds. Other ultrasounds, such as growth ultrasounds or the week ultrasound are on indication or at your own wish.
At UltraScan, we preform our Early Pregnancy ultrasound scans from 8 weeks gestation. In this scan, we look at how many foetuses and gestational sacs are.
There are two types of pregnancies. Those that are planned and those that just happen. The pregnancies that are spontaneous will often make you wonder, when did all this happen? Apart from satiating your curiosity, it has other health-related implications. For instance, there are cases where doctors have unnecessarily induced labour because there is uncertainty about how old the foetus is.
This can result in premature birth. Barring the incredibly meticulous, tracking the exact time of conception can be, at best, a guessing game. A dating scan is a method that is used to reliably assess the age of a foetus with a maximum error of 3 to 5 days. A dating scan is for women who have the following issues:. The dating scan is done with the assistance of an ultrasound machine. After this, a device called the transducer is gently navigated across the belly to do the mapping.
This procedure can take anywhere from 20 to 30 minutes. You will need to drink water before the scan as a full bladder is one of the preconditions for taking this test. This is so because the bladder thrusts the uterus upwards giving the sonographer good visibility of the womb.

Why Get An Early Pregnancy Scan?
Trans abdominal ultrasound scan. Some warm gel is applied to your lower abdomen and a probe is used to transmit ultrasound images to the screen for interpretation. A trans-vaginal internal scan may also be required to fully assess your pregnancy. You will be asked to empty your bladder and a probe will be inserted into the vagina as far as a tampon.
The most accurate way to date a pregnancy is with an ultrasound done between 6 weeks and 8 weeks, 6 days, according to Dr. Michael.
Are you visiting our clinic for an early pregnancy scan? For the privacy of our ladies, we do not mix our firstScan sessions with ladies coming for scans such as gender or 4D. We have a range of packages to suit all ladies , including viability, dating, reassurance, previous miscarriage and IVF. At 6 weeks, baby is only around 4mm so is very small. Baby has doubled in size to 8mm by week 7, so you may leave us feeling more reassured than at 6 weeks, due to how clear we can see baby.
Because this is an early pregnancy scan, baby is very small. Internal scans offer much more accurate results and are offered to ladies under 10 weeks. You may decline an internal scan if you wish by just telling your sonographer. The scan will not hurt your baby. From the very early weeks of pregnancy, your baby is surrounded by fluid which protects them, so with either an abdominal or an internal probe, the probe will not touch your baby.
We recommend arriving at the clinic between 10 — 15 minutes before your appointment.
Early Pregnancy Scan
Why does the accuracy of the ‘due date’ matter? Dating from ultrasound scans done later than about 20 weeks is with length of pregnancy and the likelihood of a pre-term birth8 and so underpin this natural variation.
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.
