Ultrasound - What to Expect (UW Medicine)
The EDD from the early dating scan is used - if the last menstrual period is not known or is unreliable, or the dating scan differs from the last menstrual period dating by more than 5 days.
Ultrasound examinations from 12 to 22 weeks are regarded as being within 10 days of accuracy or up to 10 days earlier or 10 days later than the woman's calculated due date. Ultrasounds performed after 22 weeks gestation cannot be used to estimate the due date of the baby because the size no longer reflects the age very well. Even average babies can differ by up to 2 to 3 "weeks of growth".
These scans are only used to estimate the due date of your baby if this is all you have to go on. If you have more than one ultrasound during your pregnancy, giving you 'multiple dates', then the earliest ultrasound estimate should be used, because it will be more accurate.Baby's First Ultrasound! 6 Weeks Pregnant

No one logged in. I have two older sisters that between them have had five perfectly healthy pregnancies, and it only took them a whim to get pregnant, where I am very different from that, and people that haven't had issues getting to this place or haven't seen others struggle through it, sometimes don't have a grasp on how "we" can feel.
I think it's only natural, so don't let anyone make you feel bad about it.
Sep 27, †∑ 10 Patau Syndrome. Trisomy 13 or Patau syndrome can be discovered during an ultrasound, however many babies with this abnormality do not survive until full term. In fact if a baby is born with Patau syndrome the likelihood of them surviving past age one is only %, and the average survival rate is only days.

A dating scan is an ultrasound examination which is performed in order to establish the gestational age of the pregnancy. Dating scans also reveal other important information such as: the number of fetuses and gestation sacs. the presence of a heart beat. the size of the fetus, from which the gestational age is estimated.

First Ultrasound Anxiety!

Re: First Ultrasound Anxiety! The initial red flag indicating Spina Bifida may be present is a blood test that shows high levels of AFP, a protein produced by the baby. Sonographers will look for an opening in the spine which indicates Spina Bifida. If one is found they will look closely at the opening and determine if there is a sac covering the nerves or if it is an open lesion. The technician will also look Inside the skull of the fetus for any deformity of the cerebellum, which is often connected to open spinal lesions.
The size and smoothness of the ventricles will also be assessed and can give clues to how serious the problem is. Another indicator of Spina Bifida is when the legs of the baby are not extending and flexing properly.
Nervous about dating ultrasound
Various organs of the baby are closely looked at in a prenatal ultrasound, and about 1 in births a defect in the kidneys or urinary tract is detected. If a kidney appears enlarged in the ultrasound it is most often a blockage restricting the flow of urine. Another fairly common issue is with the valve mechanism which, when failing, allows urine to flow back into the kidney. Another problem which can be discovered with the kidneys during an ultrasound is that only one is functioning.
The amazing thing is that in this case the other kidney will usually compensate for the problem, increase in size, and function at a high enough capacity for the child to grow into a normal healthy adult.
Of course if the child ever has a problem with this kidney later in life the situation would be much more severe than an adult with two functioning kidneys. A cleft lip and palate can be discovered during a prenatal ultrasound.
A cleft lip is when there is a split in the lip that can go all the way up to the nasal passage. A cleft palate is when the roof of the mouth remains open instead of closing during the development of the fetus. If a cleft lip or palate is discovered in an ultrasound the pregnant woman will likely be sent for further diagnostic testing, as these defects can be symptoms of other abnormalities such as Van der Woude syndrome.
Treatment for cleft lip and palate varies depending on how severe the deformity is. The reason a pregnant woman is asked to fill her bladder for the ultrasound is a physical one. In early pregnancy when the uterus is still small-ish, it is often hidden behind the bowel, which inhibits the sonographers view of the fetus.
When the bladder is full it actually pushes the bowel out of the way, revealing the uterus. If the bladder is not full enough a pregnant woman will be asked to drink more water, and wait longer. This creates a cyclical effect of waiting and holding because now the original appointment time has been taken by another patient, and the woman needs to wait for a new opening.
In the end it is all worth it, but in the moment it can all be very frustrating.
After heart problems, malformations of the central nervous system are the second most commonly discovered problems. Some of the cts of the central nervous system that are assessed during a typical prenatal ultrasound include the cerebellum, lateral ventricles, and thalami.
It can be difficult to detect certain abnormalities in the central nervous system until later in the pregnancy as some parts do not become apparent on an ultrasound until as late as 30 weeks gestation.
Some disorders that can be noticed when assessing the central nervous system are, but not limited to, Microcephaly, Megalencephaly, Walker-Warburg syndrome, and Polymicrogyria. If a sonographer notices any issues in the brain of a fetus they will recommend extensive further testing, likely including an MRI.
If a genetic problem is discovered in a child all future children of that woman can be tested early on for the same abnormality, usually with a diagnostic test rather than an ultrasound. Most people feel nervous about an ultrasound because the fetus might not cooperate and give the best images, but no one expects to find out that the baby is actually not alive. One of the first things a sonographer will look for in an ultrasound is the fetal heartbeat, to ensure the pregnancy is viable.
If one is not found, it means the fetus has died in utero. Depending on what week the pregnancy is in this will be considered a miscarriage or a stillbirth depending on if it is before you after 20 weeks. If a miscarriage occurs the body will likely naturally pass the fetus in what somewhat seems like a heavy period.
