When should i have my first ultrasound

What Every Mom-To-Be Needs to Know

Moms-to-be typically look forward to ultrasounds during pregnancy more than any other prenatal appointment. It’s easy to see why! It’s fun to get a sneak peek of your bundle of joy while your OBGYN looks for specific growth and development markers. Many women look forward to learning their baby’s sex as soon as possible and wait impatiently for their 20-week ultrasound. Others want to be surprised. Whether or not you intend to learn about your baby’s sex ASAP, it’s important to keep all your ultrasound appointments.

An ultrasound, also known as a sonogram, is typically performed by an ultrasound technician or sometimes by an OBGYN. It uses sound waves to create an image of the organs inside your body. (These sound waves are not harmful to you or your baby.) Ultrasounds during pregnancy help doctors diagnose many diseases and conditions, even those not related to pregnancy.

This article will cover why and how ultrasounds are used during your pregnancy, how many ultrasounds to expect while you’re pregnant, and what your OBGYN may be looking for at each ultrasound.

Most pregnant women typically only get two ultrasounds, one at the beginning of pregnancy and one about halfway through. Other women may have three or more ultrasounds done depending on a number of factors.

Your First Ultrasound

Your first ultrasound is called the “dating” or “viability” ultrasound. It’s typically done between 7 and 8 weeks to verify your due date, to look for a fetal heartbeat, and to measure the length of the baby from “crown to rump.” At this ultrasound, you’ll also learn whether you’re having one baby, pregnant with twins, or more! You may even get to see or hear your baby’s heartbeat during this appointment.

If you have irregular periods, or didn’t have a period after coming off birth control, this ultrasound will be especially helpful in determining a more accurate due date. Your due date is important because it helps your doctor know whether your baby’s development is on track each month.

We’ll perform this ultrasound at our Madison Women’s Health clinic.

What to Expect at Your First Ultrasound

When you’re just 7 or 8 weeks pregnant, your fetus is only about two centimeters long. In order to get a close enough view of your uterus and fetus, the dating ultrasound is done transvaginally. This means the ultrasound is done internally, literally “through the vagina.” A transvaginal ultrasound can be a little uncomfortable, but it is not painful. Most would say it feels less invasive than a gynecological exam that uses a speculum.

To perform this ultrasound, your OBGYN or ultrasound tech will gently insert a narrow ultrasound wand just inside your vagina. The transvaginal ultrasound wand is also called a transducer. It’s about three centimeters around, a little larger than a tampon. It will be covered by a condom and lubricant. The wand will not reach your cervix and is safe for your baby.

You may be asked to arrive at your first ultrasound with a full bladder. Having a fuller bladder helps to put your uterus in a better position for the ultrasound.

What Your Doctor is Looking for at Your First Ultrasound

Viability of pregnancy
Fetal heartbeat
Fetal size
Single or multiple pregnancy

Genetic Screening Ultrasound

If you choose to have prenatal genetic testing done, you’ll have your next ultrasound at 12 to 13 weeks gestation. This ultrasound is also called nuchal translucency screening. It’s offered to everyone and is covered by most insurance plans. This genetic screening ultrasound is optional.

During this ultrasound, your doctor will look for indicators of chromosomal disorders. Chromosomal disorders mean that the baby received an extra chromosome at conception and could have moderate to extreme physical or mental challenges. These disorders include:

Trisomy 21, known as Down Syndrome
Trisomy 13
Trisomy 18

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 baby’s 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.

We’ll perform this ultrasound at the Madison Women’s Health clinic.

Should you Get a Genetic Screening Ultrasound?

There’s no right or wrong answer to this question. Ultimately, the decision is up to you. Here are some good questions to ask yourself as you decide whether to have the genetic screening:

Is there a family history of these genetic birth disorders?
Would I terminate my pregnancy if there was a risk of Downs Syndrome, Trisomy 13, Trisomy 18, or other genetic disorder?
Would knowing about my pregnancy’s risk of genetic defect make it easier to emotionally or physically prepare for a baby with a birth defect?
Would it be easier for me to cope with and enjoy pregnancy if I focus on the more likely positive outcome rather than the chance of birth defects?

Whether you choose to have genetic screening done at this time is entirely your decision. Some women prefer to have as much information as possible as early as possible, while other women do not. If you’re still uncertain, you can discuss the pros and cons with your OBGYN.

Basic Anatomy Scan Ultrasound

This is the ultrasound that people look forward to the most! The full anatomy ultrasound is typically performed at about 20 weeks, or 5 months. As the name implies, this ultrasound will look at all the baby’s organ systems to make sure they’re present, are a normal size and shape, and are in the right location.

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 minutes—if your little one cooperates! If you’ve got an extra squirmy baby who is “camera shy,” it could take a few hours to get all the images that we need. Don’t worry, we have a lot of tricks to encourage your baby to change positions—everything from asking you to lay on one side and then the other, emptying your bladder or filling it, maybe even walking around. We’ll do whatever it takes to get the images we need to track your baby’s growth and development.

What Your OBGYN is Looking for at a Full Anatomy Scan

During the full anatomy, 20-week ultrasound, you can find out if your baby is male or female. If you want the sex to be a surprise, be sure to tell your technician know ahead of time so they don’t accidentally let it slip. When the scan is complete, Meriter will even send you a link to view some fun photos of your baby!

Your ultrasound technician will capture a large number images and measurements:

limbs: arms, legs, feet, hands
torso: chest, heart, kidneys, stomach, bladder, diaphragm, genitals
head and face
spine
umbilical cord
amount of amniotic fluid
location, size, and shape of your placenta
length of your cervix

After your ultrasound technician has captured all these images and measurements, your OBGYN will review the pictures and look for abnormalities such as congenital heart defects or cleft lip or palate. They’ll discuss their findings with you and help you understand what you’re looking at in the different images.

If everything looks normal and there are no other issues during your pregnancy, the next time you’ll see your baby is when he or she is in your arms! In the meantime, you can enjoy those 2D or 3D photos of your baby!

This ultrasound will be performed at UnityPoint Health – Meriter Hospital Center for Perinatal Care.

“Extra” Ultrasounds

Sometimes, women need additional ultrasounds during pregnancy. Your OBGYN may ask you to come in for additional ultrasounds to check your:

Cervical length: if your cervix is shorter than expected, you may need to have your cervix checked regularly to be sure it stays closed so that you can maintain your pregnancy. If the cervix continues to shorten or thin, you may need a cerclage to help strengthen it until it’s time to deliver your baby. Cervical length ultrasounds occur at 16, 18, 20 and 22 weeks and are done transvaginally.
Placental location and size: if your placenta is too small, if it is in an abnormal location or if it is an abnormal shape, then we will need to monitor it and the growth of your baby with regular ultrasounds. Your placenta is responsible for passing blood and nutrients to your baby, so it’s important thrat it is growing correctly.

You may need growth ultrasounds if you have:

hypertension
diabetes
high BMI (body mass index) going into pregnancy
preeclampsia
indicators that your placenta or uterus is not growing appropriately

Sometimes, growth ultrasounds are needed to check that your baby’s growth is continuing along the growth curve. They’re 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.

What to Expect at a Growth Ultrasound

These ultrasounds take less time than the full basic anatomy ultrasound because there are fewer measurements required. The ultrasound technician will measure the baby’s head circumference, bi-parietal diameter, abdominal circumference, and femur length.

What Your OBGYN is Looking for at Growth Ultrasounds

Your OBGYN is looking to see if your baby is staying on its growth curve. We will also use the measurements to estimate your baby’s weight. A large or extra large baby isn’t typically concerning. An extra-small baby or a baby who does not grow according to their growth curve could mean that the baby is not getting enough nourishment through the placenta and may need to be delivered early.

2D, 3D, and 4D Ultrasounds

2D ultrasounds are the black and white images that you’re probably used to seeing. To an untrained eye, they can look pretty fuzzy or obscure. However, they give the best definition of the structures of your growing peanut and are considered the “gold standard” of diagnostic imaging.

3D images are especially popular among parents-to-be who want to enjoy those cute baby pictures even before the baby is born! These pictures show facial features and look much more baby-like than the kind of obscure 2D images. 3D ultrasounds have usefulness beyond the cuteness factor, however! In the case of abnormalities of the spine or palate, 3D ultrasounds can help your OBGYN get a better idea of the severity.

4D images are like a 3D image, but show the baby moving around. They’re like getting to see a live action video of your little one. These are less commonly done because they don’t actually help with diagnoses. Depending on which perinatal center you go to, you might receive a link to view your ultrasound images or videos online.

While there are some stand-alone ultrasound centers offering to tell you your baby’s sex early on or to give you keepsake 3D or 4D images, these aren’t necessary and are rarely covered by insurance. You’ll find out everything you need to know during your appointments at the perinatal center — and those appointments will be covered by your insurance.

The best place to have an ultrasound performed is always at a clinic, where you will have access to a physician who has been trained in interpreting the images. At Madison Women’s Health, we’re happy to print off pictures for you to put in your baby’s scrapbook — or anywhere else you’d like to display those “coming soon” photos.

Final Thoughts

Ultrasounds during pregnancy are a fascinating way to get a glimpse of your developing baby. Don’t be afraid to ask your OBGYN for more details about genetic screening as you determine whether that is something you want done. And make sure you’ve set aside a good amount of time for your ultrasounds — especially the all-important full anatomy scan!

North Valley Women's Care: OBGYNs

You’ve taken a home pregnancy test and it came back positive. Now, what are your next steps to get the best care for your baby?

Call your local Glendale OBGYN to inform them of the home pregnancy test results and to schedule an appointment to confirm the pregnancy at the office.

The next step from there, scheduling your baby’s first ultrasound.

When should you get your first ultrasound?

Although ultrasounds can be performed as early as 5 weeks of pregnancy, doctors typically recommend that you schedule your first ultrasound when you are between 6-8 weeks pregnant.

Types of Ultrasound Exams

At this early stage of the pregnancy, the transvaginal ultrasound and the transabdominal ultrasound are most commonly used.

The Transvaginal Ultrasound is more accurate for getting measurements and a heartbeat this early in the 1st trimester.

This exam uses a probe transducer that is inserted into the vagina to get a look at the uterus from a closer angle.

It will show the growth of the gestational sac as early as a week before it is detectable on a regular transabdominal sonogram.

The Transabdominal Ultrasound uses the traditional transducer wand across the abdomen to send sound waves to the pelvis, which returns an image to the screen where you see your new child.

This exam can also be used to view and monitor the cervix, ovaries and the bladder while you are pregnant.

What will the first ultrasound tell you?

This is quite an experience for the mother. This is when you hear your little one’s heartbeat for the first time.

While you are in awe of what is going on inside of your body, the doctor is taking necessary measurements to learn more about the growth and approximate age.

The measurements taken include the size of:

The gestational sac
The yolk sac
The fetal pole

At about 6 weeks the Crown Rump Length (CRL) can also be used in the 1st-trimester measurements to assist with growth and age.

The CRL is one of the best estimations of gestational age in early pregnancy.

The ultrasound will pick up the heartbeat to measure the heart rate to make sure it is within a normal, healthy range.

When all measurements are gathered, the doctor has a better picture of when conception occurred and can determine a more accurate due date.

This ultrasound is such an exciting experience.

Often pictures of the pea-sized embryo are provided for you to share the wonderful news with friends and family when you are ready to do so.

What are the next steps for you and the family?

As part of your prenatal care, the health of both you and your child are now monitored very closely throughout the next 8 months.

As preferred Glendale, AZ women’s specialists who work with patients from the greater Phoenix area, we highly recommend that you maintain routine monthly appointments to check on the progress and the well-being of the baby and yourself.

The monthly appointments will also help create a more positive experience during pregnancy, as questions and concerns can be addressed during these times.

The Gender Reveal!

There are many milestones that you will experience while pregnant. One of the most exciting appointments you will have is finding out the gender.

In your 2nd trimester, between weeks 15 and 16, you will be scheduled for another ultrasound appointment to see whether you are having a boy or a girl.

These pictures make for a wonderful “We’re Expecting!” announcement.

Then, 3-4 weeks after learning the gender, your Glendale OBGYN will do a detailed anatomy ultrasound. This will be scheduled about the time you are 18 to 20 weeks pregnant.

Get a Sneak Peek!

During this exciting time, parents can’t wait to meet their little one. As the baby develops it is amazing to see his or her features as they form.

Many OBGYNs in Glendale and in the Phoenix metro area offer 3D and 4D ultrasounds.

At our Glendale location, we know that patients much prefer the 3D and 4D technology as it far outweighs the visual quality and effects of the typical 2D sonograms that appear on a black and white screen.

The higher quality imaging can be performed during the 3rd trimester to get the best pictures.

Get the Most Out of Your Maternity Journey

These sneak peeks of the baby make for the most memorable photos as well as a great gift to share with friends and family.

Babies are a precious joy. From the day you find out you are pregnant you enter into an experience that is full of awe as you get to see your little one progress and grow in your womb.

With today’s technology, you get clear, detailed pictures to share with others during this exciting time.

Trust the Absolute Best that Phoenix Has to Offer for Your Prenatal Care

Our Glendale OBGYN facility serves the greater Phoenix area. Our patients come from a broad radius to receive the best in prenatal care.

We are pleased to offer our patients the latest in this visual technology to help monitor the health and growth of your precious bundle.

Seeing your baby as your delivery day draws close only increases the anticipation for his or her arrival. Enjoy this time with advancements made in ultrasound imaging to get close to your child before he or she is in your arms!

We know there are lots of questions for expecting moms. We are here to help you along this beautiful journey.

When to do the first ultrasound during pregnancy - "happy days" for screening of the 1st trimester

The world of a modern woman is always full of important events, meetings and an endless series of pre-planned things. When pregnancy occurs, many planned events can be moved from “expected” to “impossible” or simply postponed indefinitely. It is quite difficult to worry in advance and reschedule an important event at the most appropriate time, because planning events against the backdrop of pregnancy is a very difficult science. nine0003

Therefore, when pregnancy occurs, it is advisable to draw up at least an approximate “life plan for 9 months”. For example, it is known that maternity leave is most often preceded by unspent regular leave, and registration for pregnancy is preceded by the fact that a pregnancy has occurred and is developing normally.

Many events will now depend on how the new life develops. So, when a multiple pregnancy is diagnosed, not only the estimated due date will change, but maternity leave will come 14 days earlier, and the beginning of unspent leave will move with it. Therefore, one of the first steps in the event of a desired pregnancy is the passage of an ultrasound examination (ultrasound). Scientific and technological progress is rapidly changing the whole world, including the state of the prenatal ultrasound diagnostic service. Opportunities are changing, and with them the timing of the passage of research, which I would like to dwell on in more detail. nine0003

When to do an ultrasound scan during pregnancy

In 2012, the regulation “Decree of the Health Committee of the Government of St. Petersburg No. 39-r”1 came into force in St. Petersburg. Based on the above document, for a full-fledged ultrasound screening, it is desirable to undergo a study in “... the first trimester: 11 + 0-13 + 6 weeks; 18+0-20+6 weeks; and 32+0-34+6 weeks of pregnancy.” However, these terms apply only to uncomplicated singleton pregnancies. At the same time, early registration is limited to up to 12 weeks of pregnancy with the ensuing consequences (payment of a lump-sum allowance to women registered in medical institutions in the early stages of pregnancy, clause 2-c of Decree of the Government of the Russian Federation of October 15, 2001 N 727 (as amended on 04. 09.2012).

Therefore, at 11 weeks, a pregnant woman can be registered when establishing the fact of a developing pregnancy , for which ultrasound "... in the first trimester" is recommended. Most doctors recommend doing it at terms 7-8 weeks of pregnancy , because it is at this time that the heartbeat of a developing embryo is always determined as a sign of the physiological development of pregnancy.

The next obligatory steps in the ultrasound are screening. The entire pregnancy is divided into three periods (trimesters) and ultrasound plays an important role in each. nine0003

What is the diagnostic window for ultrasound during pregnancy

The first screening study is carried out from 11 weeks 0 days of pregnancy to 13 weeks 6 days of pregnancy. These limits are adopted for the timely detection of pathological conditions that determine the prognosis for the health of the fetus. Theoretically, any pregnant woman can apply for an ultrasound both at the beginning of the eleventh and at the end of the thirteenth week - the entire period is screening. However, among doctors who have dedicated their lives to prenatal ultrasound diagnostics, there is an opinion about the most preferable period in each screening period - the so-called " diagnostic window" or "happy days" .

Terms of fetal ultrasound examination

Legally regulated period (order KZ SPb No. 39-r dated 02/01/12)	Optimal timing/happy days
-	7-8
11 weeks 0 days – 13 weeks 6 days	12 weeks 2 days - 12 weeks 4 days
18 weeks 0 days – 20 weeks 6 days	20 weeks 0 days - 20 weeks 6 days
32 weeks 0 days – 34 weeks 6 days	32 weeks 0 days - 33 weeks 3 days

Diagnostic window in the 1st trimester of pregnancy

For the first screening study, these days include the interval from 12 weeks to 12 weeks. 2 days to 12 weeks 4 days . It is in this interval that the fetus has already grown enough to evaluate the smallest organs (eye lenses, heart), and the probability of ascertaining the most important morphological changes is significantly higher than at 11 weeks 0 days. On the other hand, each day lived by the baby increases not only the height and weight of the body, but the quality of the picture on the ultrasound machine.

According to various authors, the frequency of congenital pathology reaches 5%, and for patients in this group it is especially important to identify the problem at an early stage. In such special cases, it may be necessary to expand the range of diagnostic procedures, including prenatal karyotyping (obtaining samples of fetal tissue or amniotic structures in order to determine its karyotype). It takes time to carry out these procedures, from preparing the necessary tests for a pregnant woman, ending with directly invasive diagnostics and obtaining results about the health of the fetus. nine0003

In some cases, the established disease of the fetus raises the question of the impossibility of prolonging the pregnancy. According to the current legislation of the Russian Federation, the procedure of medical termination of pregnancy by the decision of the woman can be performed "... no later than the end of the twelfth week of pregnancy", but "... not earlier than 48 hours from the moment the woman applied to the medical organization for artificial termination of pregnancy" (clause 3.1, clause 3-b of article 56. Federal Law No. 323 of November 21, 2012)2. In other words, if a patient goes for an ultrasound scan at 12 weeks 5 days, if a serious pathology is detected, she is no longer sent for an artificial medical abortion, but for an abortion, which is a more complex and traumatic procedure. Therefore, when asked about the best rock for the first screening, almost any practitioner will answer: "up to 12 weeks 4 days" .

Diagnostic window in the 2nd trimester of pregnancy

The second screening period occurs at 18 weeks. 0 days and ends at 20 weeks 6 days pregnant . "Lucky days" is considered the entire twentieth week: 20 weeks. 0 days - 20 weeks 6 days . Not all the subtleties of the architectonics of the main organs can be considered so successfully, especially in pregnant women with increased body weight at 18 weeks of pregnancy. If so-called "markers of chromosomal problems" are detected, it may be necessary to perform prenatal karyotyping (obtaining fetal blood or amniotic fluid), which may take some time. nine0003

The collection of the material itself takes several minutes, but the preparation of the pregnant woman (examination, obtaining the results of blood and urine tests, etc.), transporting the material to the laboratory, examination and obtaining the results can take several days. If serious deviations in the state of health of the fetus are detected, in order to resolve the issue of further management tactics, the pregnant woman is sent to undergo a prenatal consultation consisting of an ultrasound doctor, a specialist in the field to which the identified disease belongs (for example, a surgeon, neurosurgeon, cardiologist, etc. ) . nine0003

Prior to the new regulation, the second screening period ranged from 18-22 weeks, even earlier than 18-24 weeks of pregnancy. According to WHO recommendations, the fetus becomes viable from the 22nd week of pregnancy, therefore, before this period it is very important to obtain all possible information about its condition and form a prognosis for health and later life. That is why now there is a restriction regulated by law, so that if serious problems with the health of the fetus are detected, all additional diagnostic procedures should be carried out in a timely manner and, if necessary, terminate the pregnancy without violating the Legislation of the Russian Federation2. nine0003

Diagnostic window in the 3rd trimester of pregnancy

The third screening period (32 weeks 0 days - 34 weeks 6 days of pregnancy) has two main objectives: the exclusion of congenital malformations with late manifestation and assessment of the fetal condition. Issuance of a referral for the passage of the third ultrasound along with maternity leave of 30 weeks. 0 days of pregnancy potentiates untimely early appeal of pregnant women for the third screening ultrasound before the period of 32 weeks 0 days, which in turn may require a second planned ultrasound in the "scheduled time". A later turnout (after 34 weeks) reduces the quality of the ultrasound picture obtained by changing the relationship between the amount of amniotic fluid and the volume of the fetal body towards the latter. Therefore " happy days" the third trimester can be considered the period 32 weeks 0 days - 33 weeks 3 days of pregnancy .

Unscheduled ultrasound at any stage is required, as a rule, only in case of complicated pregnancy, therefore, it is prescribed only according to indications and is performed regardless of the gestational age.

Early pregnancy ultrasound

Two stripes on the test is always a complete surprise for a woman, even if she already knows about her position in her soul. After the first confirmation, the girl most often wants to see the baby with her own eyes and make sure that he is developing normally. This can be done using an instrumental method such as ultrasound. Usually, expectant mothers, especially expecting their first child, have a lot of questions. nine0003

How to avoid missing ectopic and non-developing pregnancies

Often, pregnant women at the very beginning are afraid of two conditions - an ectopic or missed pregnancy. Especially experienced by those who have already experienced it once.

In an ectopic pregnancy, the fertilized egg does not reach the uterus and is implanted in other places - most often these are the fallopian tubes. If nothing is done, the embryo will grow and burst the tube. In this case, the woman can not be saved. Therefore, an ectopic pregnancy should be terminated without hesitation. Since the embryo is not removed separately, the entire tube is cut out. This can be done twice in a lifetime, after which pregnancy occurs only after artificial replanting using IVF. An ectopic pregnancy can be suspected indirectly by the level of β-hCG, but only the presence of a fetal egg in the uterus on ultrasound clearly refutes it. nine0003

But the experiences of the expectant mother do not end there. Frozen pregnancy is impossible to predict. In some cases, doctors shrug their shoulders, and why this happened remains unknown. It is dangerous to wait for a non-developing egg to come out by itself for a long time, since it can begin to decompose, and the uterus can become inflamed. Up to 6 weeks, the gynecologist can offer a less traumatic medical interruption, and after - classic abortive methods. It is possible to unambiguously identify a frozen one only by ultrasound - it shows that the fetal egg is smaller than it should be for its term or a heartbeat is not heard. At random, such a diagnosis is never made, because the life of the unborn child depends on it, and most often an ultrasound is prescribed again after a few days. If it turns out that the dimensions have not changed, and there is still no heartbeat, then - alas! nine0003

Why early ultrasound is needed

Ultrasound diagnostics is a safe method that has no contraindications. But it is pointless to do it before 4-5 weeks, the fetal egg cannot be seen so early. In this case, a transvaginal probe is used for ultrasound. In public clinics, the first ultrasound diagnosis is carried out as part of the first screening at 12 weeks, and earlier it is prescribed only if the woman herself or her doctor is worried about something:
