Prepare Yourself For Testing
Usually an ultrasound technician or your ob-gyn will perform an ultrasound. Get ultrasounds at an accredited facility, not at an unaccredited place at the mall. An unaccredited facility can either miss something or find something that will upset you thats not really there, said Dr. Beryl Benacerraf, professor of radiology and of obstetrics, gynecology and reproductive biology at Brigham and Womens Hospital and Harvard Medical School in Boston. Yes, you will get pictures of the baby, but an ultrasound is not primarily a photo shoot. Its O.K. if the result is a blurry picture of the babys elbow, as long as your health care provider gets the necessary medical information.
Its common to get a transabdominal ultrasound, meaning that the ultrasound wand, or transducer, is pressed up against the abdomen, lubricated with gel. But its possible you will need a transvaginal ultrasound, meaning that the transducer is placed inside your vagina. Transvaginal ultrasounds may be necessary in very early pregnancy, to look at the shape of your uterus, if youre obese or if your medical team has trouble seeing things with a transabdominal ultrasound. You can ask to insert the transducer yourself if that would make you more comfortable, said Dr. Joshua Copel, a professor of obstetrics and gynecology at Yale, who offers this option.
Current Practice In Iceland
At the time of the present study, Iceland had 320,000 inhabitants, with 70% living in the greater capital area. Then and now, the Icelandic healthcare system resembles the other Nordic Welfare states with some variations . Public primary healthcare is intended to represent the entry point in most instances. There is, however, no systematic referral or gatekeeping system , and private specialists can be directly sought for a relatively affordable fee.
As previously explained, Icelandic women who become pregnant have, since before this study started, easy access to private gynaecologists who employ ultrasound equipment as part of their clinical routines. A high number of women consequently have their pregnancies confirmed by a scan, before signing up for public antenatal care . The cost for such a consumer-initiated specialist consultation with ultrasound scanning has a maximum fee of 117 Euro . The content of the private consultations in early pregnancy may evidently vary. It can be assumed that a confirmatory scan is performed, and that information about the optional 1114week screening programme is provided. Beyond this, we have limited knowledge about the expectant parents` ideas about, and experiences with, ultrasound in the early phases of pregnancy, from a general population perspective. We also lack knowledge about the parents information level and decision-making related to the foetal screening programme in week 1114.
You May Need Growth Ultrasounds If You Have:
- high BMI going into pregnancy
- indicators that your placenta or uterus is not growing appropriately
Sometimes, growth ultrasounds are needed to check that your babys growth is continuing along the growth curve. Theyre done at 28, 32, and 36 weeks. One way doctors estimate whether your baby is growing as expected is by measuring your fundal height. Fundal height is the number of centimeters from your pubic bone to the top of your uterus. This measurement typically increases about 1 cm each week. If your uterus has not grown appropriately in the last month, your OBGYN will surmise that your baby is also not growing and will want to perform monthly growth ultrasounds.

When Is The First Ultrasound During Pregnancy
Your doctor will usually wait until at least six weeks to perform the first ultrasound. However, if your periods are irregular or youve had a history of complications, such as an ectopic pregnancy, a miscarriage, pain, or bleeding, your doctor might send you for an earlier scan, says Susan Kinnear, manager of diagnostic imaging at Hamilton Health Sciences Centre and director at large for Sonography Canada. Generally, if your period is regular and you know the guesstimated date of conception, you wont have your first ultrasound until you are closer to the end of the first trimester, at 11 to 14 weeks.
Location Of The Embryo
The technician is looking at whether the embryo implants in the uterus. If it implants outside of the uterus, this indicates an ectopic pregnancy, which happens when a fertilized egg implants in the fallopian tube or somewhere besides the uterus. Where the embryo implants is also important as it can be higher or lower in the uterus.

Confirmation Or Exclusion Of Intrauterine Pregnancy When No Yolk Sac Or Embryo Is Seen
When a sonogram is performed on a woman with a positive pregnancy test, a fundamental question concerns where the pregnancy is located: intrauterine or ectopic. The question is answered based on the sonographic findings in the uterus and adnexa. The sonographic finding that is definitive for a gestational sac in either location is a fluid collection containing a yolk sac or an embryo with cardiac activity. In the absence of such a fluid collection, the diagnosis is less straightforward. We will consider a number of scenarios involving various potential sonographic appearances of the uterus and adnexa.
What To Expect At A Full Anatomy Scan Ultrasound
The full anatomy scan is a transabdominal ultrasound. It uses a transducer that looks a lot like a store checkout scanner. The ultrasound technician will put warm ultrasound gel on your stomach and then slide the transducer in the gel around your stomach. The gel helps the sound waves travel through your skin.
Tip: Come to your appointment with a relatively full bladder. This will make it easier for your ultrasound technician to get better images of your baby.
Because there are so many things to look for, this ultrasound will take at least 45 minutesif your little one cooperates! If youve got an extra squirmy baby who is camera shy, it could take a few hours to get all the images that we need. Dont worry, we have a lot of tricks to encourage your baby to change positionseverything from asking you to lay on one side and then the other, emptying your bladder or filling it, maybe even walking around. Well do whatever it takes to get the images we need to track your babys growth and development.

How Soon Can An Ultrasound Confirm Your Pregnancy
In early pregnancy, an ultrasound is done to confirm if the pregnancy is viable or date the pregnancy if the mother is unsure about her last menstrual cycle. Later on, it is done periodically to determine fetal health and expected date of delivery.
Two types of early ultrasounds may be performed: abdominal ultrasonography and trans-vaginal ultrasonography.
In an abdominal USG:
- A small gestational sac or yolk sac is seen in the 5th week of pregnancy.
- A fetal pole, the first sign of a viable pregnancy is seen in the late 5th or early 6th
- In the mid-6th to 7th week, a fetal heartbeat can be seen, though the Doppler does not detect the sound until much later.
In a trans-vaginal USG:
- A gestational sac is usually seen in the 3rd to 4th
- A fetal pole is seen in the 5th to 6th
6th to 7th week is considered the best time for an early ultrasound as a fetus with a heartbeat is visible.
When Can You Take A Home Pregnancy Test
A pregnancy test detects the pregnancy hormone hCG in the blood or urine to determine if a woman is pregnant. How early pregnancy can be detected depends on finding the hCG hormone. hCG can be detected in urine or blood after implantation, which occurs on average, about 9 days after fertilization. Some home pregnancy tests claim to detect hCG as early as 4 days before the next expected period yet that claim depends on your luteal phase and how soon the embryo implanted. Quantitative blood tests can detect hCG levels as low as 1 mIU/mL, while urine tests have published detection thresholds between 20 and 100 mIU/mL, depending on the brand.

What Is An Ultrasound
An ultrasound is a painless diagnostic test that most women will receive during pregnancy. High-frequency sound waves travel into your uterus, and they bounce back from the fetus as vibrations. The echoes are translated into electrical signals that are projected as black-and-white pictures on a monitor. The images display your baby’s soft tissues and organs.
How Early Can You See A Baby On An Ultrasound Scan
Peek A Baby offers Early Pregnancy Reassurance Scans from 6 weeks of pregnancy.
In viable pregnancies, trans-vaginal scans should be able to detect a gestation sac from 5 weeks of pregnancy. A yolk sac can be seen at 5 1/2 weeks gestation.
Trans-abdominal scan may be less accurate at this early 5 week stage. The quality of ultrasound images produced by both trans-vaginal and trans-abdominal scans will be affected by your BMI and the position of the baby. Higher BMIs can effect the visibility of the pregnancy especially when the pregnancy is so early.
Ultrasound can usually detect a fetal heartbeat at 6-7 weeks of pregnancy, when the baby’s length or crown-rump length is 7mm.
If the CRL is less than 7mm and no heartbeat is seen, this may be because the embryo is too young. You will be offered a re-scan. Often times ladies date their pregnancies based on their last period dates however, these dates can be affected by numerous variables and as such, are not always correct. This can mean that the pregnancy is not as far along as suggested by your period dates. We will be able to see the pregnancy, however not be able to confirm a heartbeat and will therefore as you back for a free rescan at a time when the sonographer recommends.
If the CRL is > 7mm and no heartbeat is seen, sadly this means you have suffered a miscarriage.

Expected Ultrasound Results By Week In Early Pregnancy
|Fetal pole possible fetal heartbeat|
|6.5 to 7 weeks||Fetal heartbeat|
These are averages for when specific early pregnancy developmental points become detectable by transvaginal ultrasound. Generally, abdominal ultrasound is less sensitive and may not detect these milestones until a week or later in the pregnancy.
Remember that any uncertainty about the date of ovulation could affect what the ultrasound will show at any point in early pregnancy.
What Happens After An Ultrasound
For most women, ultrasound shows that the baby is growing normally. If your ultrasound is normal, just be sure to keep going to your prenatal checkups.
Sometimes, ultrasound may show that you and your baby need special care. For example, if the ultrasound shows your baby has spina bifida, he may be treated in the womb before birth. If the ultrasound shows that your baby is breech , your provider may try to flip your babys position to head-down, or you may need to have a cesarean section . A c-section is surgery in which your baby is born through a cut that your doctor makes in your belly and uterus.
No matter what an ultrasound shows, talk to your provider about the best care for you and your baby.

How Should I Prepare For An Ultrasound
There is no special preparation for the ultrasound test. Some doctors require you to drink 4-6 glasses of water before the test, so your bladder is full. This will help the doctor view the baby better on the ultrasound. You will be asked to refrain from urinating until after the test.
Some doctors allow you to video the ultrasound so that you can take it home. Ask your doctor if this is an option. If it is, you will need to bring a blank videotape or DVD to your appointment.
If The Scan Shows Your Baby Is More Likely To Have A Condition What Happens Next
If the scan shows your baby is more likely to have a condition, the sonographer may ask for a second opinion from another member of staff. You might be offered another test to find out for certain if your baby has the condition.
If you’re offered further tests, you will be given more information about them so you can decide whether or not you want to have them. You’ll be able to discuss this with your midwife or consultant.
If necessary, you will be referred to a specialist, possibly in another hospital.

Are Fetal Ultrasounds Safe
Medical 2D ultrasound has been used in pregnancy for over 50 years. Many studies have been done to determine if a medical ultrasound is safe. There have been millions of prenatal ultrasounds over the past few decades with no confirmed health risks for the baby or the mother. Ultrasound is not an X-ray and does not use ionizing radiation.
All ultrasound scans are ordered by a doctor, midwife or nurse practitioner. They must be done by properly trained practitioners who have special knowledge and skill in fetal ultrasound.
When Is The Earliest An Ultrasound Can Diagnosis Pregnancy
You may have had a positive pregnancy test but when will you be able to have an ultrasound to confirm the pregnancy?
The first part of the pregnancy that can be seen is the gestational sac. The gestational sac can be seen around cycle days 32-35, which is about 18-21 days after ovulation/fertilization. However, sometimes it can take a couple of days longer to see the gestational sac on transvaginal ultrasound. On abdominal ultrasound, the sac can be seen several days later.
The gestational sac is a structure that surrounds the embryo and can be seen even before the embryo is visible. About 7-10 days later, the embryo can be seen on transvaginal ultrasound . You can likely now also see the fetal heartbeat.
Usually, you cannot see the pregnancy on a transvaginal ultrasound until a blood hCG level reaches at least 1,500.

What To Expect From Your First Pregnancy Ultrasound
Anticipation is a big part of pregnancy. You wonder what your baby will look like, and more important, whether he or she will be healthy. An ultrasound offers an early peek inside the womb, and a chance to learn a bit more about your babys expected due date and well-being.
A first-trimester ultrasound is usually done 7 to 8 weeks from the first day of your last menstrual period, says Rebecca Jackson, MD, assistant professor of obstetrics and gynecology at the Sidney Kimmel Medical College at Thomas Jefferson University in Philadelphia, PA. The main thing is to confirm pregnancy dating to make sure we have an accurate due date, to make sure that were able to see the babys heartbeat, and to see if theres one, or more than one, fetus.
Your doctor can also use this test to screen for genetic problems, as well as to find any issues with your uterus or cervix. If youre anxious to learn the babys sex, youll have to wait a bit longer. The gender reveal, as well as more info about your babys anatomy, will come at your next ultrasound, which happens between weeks 18 and 22 of your pregnancy.
The typical ultrasound creates a two-dimensional cross-sectional image of your baby. Some facilities advertise 3D and even 4D ultrasounds, which produce a more photograph-like image of your baby. These high-tech scans arent necessary, but they may be preferable if you suspect your baby has an abnormality like a cleft palate thats harder to see clearly with 2D imaging.
What Your Doctor Is Looking For At The Genetic Screening Ultrasound
This ultrasound will be an anatomical scan. Your doctor will look to see if all four limbs are present. They will also look for basic structures in the brain, the stomach, the bladder, the nasal bone, and last but not least, something called nuchal translucency. Nuchal translucency is a fluid sack at the back of the babys neck that is filled with lymphatic fluid. There are correlations between the size of that sack of fluid and the likelihood that the fetus could be affected by a major chromosomal disorder.
After the ultrasound has been performed, your OBGYN will interpret the results and share the information with you. You may also meet with a genetic counselor who could recommend having additional tests done to verify the ultrasound results.
Keep in mind that ultrasound screenings for other genetic disorders or anatomic abnormalities become more accurate further into the pregnancy.
Well perform this ultrasound at the Madison Womens Health clinic.

When Can An Ultrasound Confirm Pregnancy
On ultrasound, how early pregnancy can be detected depends on seeing the gestational sac, or the embryo. Once a pregnancy has advanced past the first 6-8 weeks, it is usually easier to follow by sonography as more information is obtained in real time. In general, pregnancy is detectable 25 days after ovulation by transvaginal sonography .
Medical Issues To Consider
Ultrasound is a safe, painless and non-invasive procedure. Many parents consider the ultrasound as an opportunity to see their unborn child, and perhaps discover its sex. However, you should remember that the ultrasound is a diagnostic procedure and, in some cases, it may suggest that a fetus has an abnormality. Further tests are usually needed to confirm the diagnosis.
