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.

If you are unsure of your dates or have irregular cycles we do ask that you have a scan two weeks after your first positive pregnancy test.

There is no strict definition of ‘large for dates’ (macrosomia), but it is generally You will be offered an ultrasound scan to estimate the growth of the baby and to.
Routine ultrasound should not be offered or requested simply to confirm an ongoing early pregnancy in the absence of any clinical concerns, symptoms or specific indications. The purpose of the scan is to confirm viability, accurately establish gestational age, determine the number of viable fetuses, evaluate gross fetal anatomy and, if requested, assess the NT as part of the risk assessment for aneuploidy.

Week 7 Ultrasound: What It Would Look Like
A beautiful, supremely talented young friend of our family recently fell victim to a terrible medical mistake. Newly married, she was having some pelvic pain and bleeding, and the doctor who saw her diagnosed a probable ectopic pregnancy — an embryo that develops outside the womb. Concerned that such pregnancies can turn life-threatening, the doctor prescribed the standard treatment: methotrexate, a drug used for chemotherapy and to help induce abortions.
When our friend returned to be checked a few days later, the imaging revealed that in fact, the pregnancy had not been ectopic; it was in place, in her uterus. But because she had taken the methotrexate, a known cause of birth defects, her pregnancy was doomed. She soon miscarried.
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.

If you bleed in early pregnancy it does not always mean that you are having a miscarriage; in fact it is quite common. One in four women will bleed in early pregnancy, many of whom go on to have a healthy baby. It is also possible that you will have tests and investigations but the reason for your bleeding will not be found. Your doctor is likely to begin with an internal examination to feel the size of your uterus and to look for any obvious visible sign of bleeding.
If you have been bleeding, you will likely be offered a vaginal ultrasound because it offers the best possible view of your pregnancy. A vaginal ultrasound is a narrow probe, which is put inside the vagina; it feels much like an internal examination and is quite safe.

Ultrasounds show the caregiver a number of things. Pregnancy ultrasounds can be very useful and provide a lot of information, but it is important to remember that they also have their limitations. The accuracy of a pregnancy ultrasound will very much depend on the qualifications, skill and experience of the ultrasonographer performing the examination, as well as their skill at interpreting the images.
Accurate ultrasound findings also depend on the stage of the pregnancy and what the ultrasound examination is trying to achieve. For example, it is very easy to determine the position of an unborn baby, but it requires a very experienced ultrasonographer to detect pregnancy problems or physical abnormalities in the baby. NOTE: Some maternity caregivers purchase ultrasound machines to perform ‘informal’ ultrasounds at every pregnancy visit in their private rooms. This is not an essential part of routine pregnancy visits and you can decline having this done if you prefer.
Generally, most maternity caregivers have very limited training in the use and interpretation of ultrasounds and can only provide a small amount of information. Later ultrasounds after 18 weeks can show the position that the baby is lying in and detect many obvious physical abnormalities such as a cleft lip or a heart defect.
Ultrasounds cannot reveal a baby’s genetic ‘make-up’ and this type of information can only be obtained through genetic tests. Ultrasound images are generally limited by the scope of the probe and where the sound waves can reach. Therefore during the first half of pregnancy, the whole baby can be seen on the screen, often moving their arms and legs, but the details of their face are usually less distinct.
During the last half of pregnancy, the whole baby cannot be viewed all at once, but you can usually see clearer images of their facial features, hands or feet. Your caregiver may order an ultrasound or more than one at various times during the pregnancy, for different reasons.
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.
Early Pregnancy Scans are not routinely offered on the NHS but you may have scan is often called a viability scan) and to calculate the date when your baby is.
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. With only a yolk sac to see, we can confirm that the pregnancy is in the right place or not ectopic. The image above is now showing a 6 week pregnancy at this point is is possible to see the embryo and measure the gestational age quite well, but it is not always possible to see a heartbeat at this time.
If the heartbeat is not visible it can cause a lot of worry waiting to scanned again in a week or so time so it’s always best to avoid this situation from occurring.

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. The most accurate time is between 8 and 11 weeks gestation. This is because the fetus is growing so quickly that there is a big difference in size from week to week. However, the accuracy of the ultrasound examination is always dependent on the skill of the sonographer and the quality of the equipment.
