What is an ultrasound? Ultrasound (also called sonogram) is a prenatal test offered to most pregnant women. It uses sound waves to show a picture of your baby in the uterus (womb). Ultrasound helps your health care provider check on your baby’s health and development.
Ultrasound can be a special part of pregnancy—it’s the first time you get to “see” your baby! Depending on when it’s done and your baby’s position, you may be able to see his hands, legs and other body parts. You may be able to tell if your baby’s a boy or a girl, so be sure to tell your provider if you don’t want to know! Most women get an ultrasound in their second trimester at 18 to 20 weeks of pregnancy.
Some also get a first-trimester ultrasound (also called an early ultrasound) before 14 weeks of pregnancy. The number of ultrasounds and timing may be different for women with certain health conditions like as asthma and obesity. Talk to your provider about when an ultrasound is right for you.
To confirm (make sure) you’re pregnant To check your baby’s age and growth, This helps your provider figure out your due date. To check your baby’s heartbeat, muscle tone, movement and overall development To check to see if you’re pregnant with twins, triplets or more (also called multiples) To check if your baby is in the heads-first position before birth To examine your ovaries and uterus (womb). Ovaries are where eggs are stored in your body.
Your provider also uses ultrasound for screening and other testing. Screening means seeing if your baby is more likely than others to have a health condition; it doesn’t mean finding out for sure if your baby has the condition. Your provider may use ultrasound:
To screen for birth defects, like spina bifida or heart defects. After an ultrasound, your provider may want to do more tests, called diagnostic tests, to see for sure if your baby has a birth defect. Birth defects are health conditions that a baby has at birth. Birth defects change the shape or function of one or more parts of the body. They can cause problems in overall health, in how the body develops, or in how the body works. To help with other prenatal tests, like chorionic villus sampling (also called CVS) or amniocentesis (also called amnio). CVS is when cells from the placenta are taken for testing. The placenta is tissue that provides nutrients for your baby. Amnio is a test where amniotic fluid and cells are taken from the sac around your baby. To check for pregnancy complications, including ectopic pregnancy, molar pregnancy and miscarriage,
Are there different kinds of ultrasound? Yes. The kind you get depends on what your provider is checking for and how far along you are in pregnancy. All ultrasounds use a tool called a transducer that uses sound waves to create pictures of your baby on a computer. The most common kinds of ultrasound are:
Transabdominal ultrasound. When you hear about ultrasound during pregnancy, it’s most likely this kind. You lay on your back on an exam table, and your provider covers your belly with a thin layer of gel. The gel helps the sound waves move more easily so you get a better picture. Then he moves the transducer across your belly. You may need to drink several glasses of water about 2 hours before the exam to have a full bladder during the test. A full bladder helps sound waves move more easily to get a better picture. Ultrasound is painless, but having a full bladder may be uncomfortable. The ultrasound takes about 20 minutes. Transvaginal ultrasound. This kind of ultrasound is done through the vagina (birth canal). You lay on your back on an exam table with your feet in stirrups. Your provider moves a thin transducer shaped like a wand into your vagina. You may feel some pressure from the transducer, but it shouldn’t cause pain. Your bladder needs to be empty or just partly full. This kind of ultrasound also takes about 20 minutes.
In special cases, your provider may use these kinds of ultrasound to get more information about your baby:
Doppler ultrasound. This kind of ultrasound is used to check your baby’s blood flow if he’s not growing normally. Your provider uses a transducer to listen to your baby’s heartbeat and to measure the blood flow in the umbilical cord and in some of your baby’s blood vessels. You also may get a Doppler ultrasound if you have Rh disease. This is a blood condition that can cause serious problems for your baby if it’s not treated. Doppler ultrasound usually is used in the last trimester, but it may be done earlier. 3-D ultrasound. A 3-D ultrasound takes thousands of pictures at once. It makes a 3-D image that’s almost as clear as a photograph. Some providers use this kind of ultrasound to make sure your baby’s organs are growing and developing normally. It can also check for abnormalities in a baby’s face. You also may get a 3-D ultrasound to check for problems in the uterus. 4-D ultrasound. This is like a 3-D ultrasound, but it also shows your baby’s movements in a video.
Does ultrasound have any risks? Ultrasound is safe for you and your baby when done by your health care provider. Because ultrasound uses sound waves instead of radiation, it’s safer than X-rays. Providers have used ultrasound for more than 30 years, and they have not found any dangerous risks.
If your pregnancy is healthy, ultrasound is good at ruling out problems, but it can’t find every problem. It may miss some birth defects. Sometimes, a routine ultrasound may suggest that there is a birth defect when there really isn’t one. While follow-up tests often show that the baby is healthy, false alarms can cause worry for parents.
You may know of some places, like stores in a mall, that aren’t run by doctors or other medical professionals that offer “keepsake” 3-D or 4-D ultrasound pictures or videos for parents. The American College of Obstetricians and Gynecologists (ACOG), the Food and Drug Administration (FDA) and the American Institute of Ultrasound in Medicine (AIUM) do not recommend these non-medical ultrasounds.
- The people doing them may not have medical training and may give you wrong or even harmful information.
- 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 (feet-down instead of head-down), your provider may try to flip your baby’s position to head-down, or you may need to have a cesarean section (also called c-section).

Is 6 weeks too early for ultrasound?
I can see my baby! – The 12 week ultrasound may be the first time parents have seen their little baby. So this is an exciting, if a little nerve-wracking time. It’s completely normal for parents to consider the possibility that their baby may not be developing as it needs to and perhaps build apprehension before the procedure.
After all, this is one of the reasons why a 12 week ultrasound is recommended. One of the benefits of having an ultrasound so early in pregnancy is that if complications are found, then parents can make an informed choice of continuing with the pregnancy or not. Medical recommendations around this issue are very important.
Ethical, religious and personal belief systems also need to be carefully balanced and weighed up. Parents need to feel as if they are fully informed and comfortable with the explanations provided by the sonographer doing the 12 week ultrasound. Follow up care by the healthcare team are equally as important.

How many times do you get an ultrasound during pregnancy?
Ultrasounds are a regular part of prenatal medical care for most pregnant women, and also provide parents with their first glimpses of their developing baby. Although these photographs make for nice keepsakes, most women need very few scans, and medical guidelines firmly state that ultrasounds during pregnancy should be performed only when there is a valid medical indication.
According to the American Congress of Obstetricians and Gynecologists, there have been no reports of documented negative effects on the fetus from diagnostic ultrasound procedures. But, the ACOG discourages the use of ultrasounds for nonmedical purposes because while there are no confirmed biological effects caused by scans, there’s always a possibility that some could be identified in the future.
“2D ultrasounds are the safest radiological modality offered to pregnant women, but as with everything, should be used in moderation,” says Monica Mendiola, MD, a practicing physician in Women’s Health at Beth Israel Deaconess HealthCare-Chelsea and an instructor in Obstetrics & Gynecology at Harvard Medical School.
Most healthy women receive two ultrasound scans during pregnancy. “The first is, ideally, in the first trimester to confirm the due date, and the second is at 18-22 weeks to confirm normal anatomy and the sex of the baby,” explains Mendiola. “As long as these ultrasounds are normal and mom’s abdomen measures consistent with her gestation, then that is all most women need.” Mendiola notes that if there are any problems with these initial ultrasounds, or if there is a discrepancy in the fetus size along the way, a repeat ultrasound is warranted.
“Additionally, if moms have medical issues such as diabetes or hypertension, then they will also receive additional scans,” she says. Above content provided by Beth Israel Deaconess Medical Center. For advice about your medical care, consult your doctor.

Can you see heartbeat at 5 weeks?
– Hearing a baby’s heartbeat for the first time is an exciting milestone for new parents-to-be. A fetal heartbeat may first be detected by a vaginal ultrasound as early as 5 1/2 to 6 weeks after gestation. That’s when a fetal pole, the first visible sign of a developing embryo, can sometimes be seen.

Can you feel kicks at 7 weeks?
When should I feel my baby move? – Before 14 weeks, the baby will be moving, but you usually won’t be able to feel it. Most of our patients come in for an ultrasound when they are around 8 to 10 weeks pregnant, to help us confirm their due date. The baby is about an inch long at this point with small limb buds, making it look like a tiny teddy bear.
- During the ultrasound, we can see the entire baby bouncing around inside the uterus in a sac of amniotic fluid.
- The first fetal movements are often described as a “fluttering.” It is often such a subtle movement that you have to be still and pay close attention to notice it.
- Some women can feel their baby move as early as 15 weeks, while others don’t notice it until closer to 20 to 22 weeks.
It varies for each person and depends on a number of factors. There’s no difference in the health of a baby whose movements are felt sooner rather than later. I frequently tell my patients about my experience when I was pregnant with twins. As an obstetrician, I was trained to use my stethoscope to listen for fetal heart beats.
I could hear their heart beats at 18 weeks of pregnancy, but even with two babies, it was close to 21 weeks before I was certain that I was feeling them move. You also should be reassured by your second trimester ultrasound, where you can see the baby moving around, even if you aren’t feeling it yet.
As the pregnancy progresses and the baby grows, the movements usually become stronger. Some of the kicks and flips might take your breath away. If the movements feel rhythmic for a few minutes, your baby probably has a case of the hiccups! Once you start to feel movement, it may be helpful to refer to a pregnancy calendar.
These calendars offer week-by-week pregnancy information and can help you track your baby’s development. A quick online search will produce several options. Having this kind of information delivered by is easy, too. Toward the end of the pregnancy, the baby is bigger and has less room to move around, so women often notice a difference in the movements.
Sharp jabs and somersaults turn into nudges, as the baby settles into a uterus that is relatively more crowded.

Can you feel kick at 7 weeks?
When can you feel baby move? – You probably won’t feel your baby kick until sometime between 16 and 22 weeks, even though they started moving at 7 or 8 weeks, (You may have witnessed the acrobatics if you’ve already had an ultrasound,) Veteran moms tend to notice those first subtle kicks, also known as “quickening,” earlier than first-time moms because it’s easier to distinguish your baby’s kicks from other belly rumblings (such as gas) if you’ve been pregnant before,

When should I worry about 7 weeks pregnant?
Cramping and/or spotting – in early pregnancy is normal. After all, there’s a lot happening inside your uterus, and even though it will be several weeks before you feel baby move, you can certainly feel plenty of cramping and pulling at this point in your pregnancy.
Also, your cervix may be more sensitive now that you’re pregnant, so at 7 weeks could happen after sex. These two pregnancy symptoms can be alarming, but know that in most cases, they’re not a sign of ectopic pregnancy or other types of miscarriage. If you were to have abdominal pain worse than typical menstrual cramps or bleeding during pregnancy at 7 weeks that’s heavier than a period, that could be a cause of worry, and you should call your doctor right away.
That said, at 7 weeks pregnant, you may very well have no symptoms at all. If that’s the case, consider yourself lucky! Some moms-to-be worry that having no symptoms at 7 weeks could be a sign of a problem, but it’s absolutely not. We’ll keep reminding you that every woman experiences pregnancy slightly differently.

Is an empty sac normal at 5 weeks?
No Yolk Sac at 5 to 6 Weeks – No yolk sac at 5 to 6 weeks of gestation may mean either that the pregnancy is less than 6 weeks along or there has been a miscarriage. Having another ultrasound in 1 to 2 weeks can determine if the pregnancy is viable or not.

How accurate is a dating ultrasound at 7 weeks?
Week 7 Ultrasound – Pregnancy Scans Week 7 ultrasounds are commonly recommended by doctors. Huggies shares what to expect and what questions you can ask here. At around seven weeks of pregnancy, it’s reasonably common for women to have their first ultrasound. This can be for many reasons but the most common is to confirm pregnancy and to check that the embryo is viable and “everything’s ok”. Other reasons to have a 7-week ultrasound are to:
- Confirm the presence of one or more embryos and gestational sacs.
- Assess the gestational age. This can also be known as a “dating scan”.
- When a mother has been experiencing blood loss, the ultrasound can identify the cause and source of the,
- Confirm the presence of a heartbeat.
- Check the size of the embryo and ensure the baby is the right size for gestational age.
- To do a general check of the uterus, fallopian tubes and ovaries.
- To ensure the embryo has implanted within the uterus and there is not an ectopic pregnancy occurring.
- When a mother is unsure about the date of her last normal menstrual period (LNMP) and to assess the embryo’s growth in relation to her menstrual history.
- When is a dating scan necessary?
- This is a scan or ultrasound which determines your expected date of confinement (EDC) based on the development of the embryo.
- A dating scan is generally done for women who:
- Are unsure about the date of their last normal menstrual period.
- For women who have an irregular menstrual history or cycles.
- For women who have recently had a miscarriage and have soon conceived again.
- For women who have recently stopped using contraception such as oral contraceptives or alternative forms of hormonal contraception.
- For women who are breastfeeding and although they may not have resumed menstruating, have conceived again.
- In any other situation, or for any other reason why confirming the gestational age of the embryo is considered important.
How big will my baby be at the 7-week ultrasound? The embryo will be measured from the top of its head, the “crown” to its bottom or “rump”. This is because it is the longest portion of the embryo’s body and provides an ideal measurement baseline of growth and development.
- The limbs and the yolk sac, though obviously important, are not the primary means of measuring growth.
- An average length of the embryo at 7 weeks is anywhere between 5mm-12mm.
- The average weight is less than 1 gram.
- Obviously, every pregnancy is unique and individual factors influence the size of the embryo at this early stage, and the embryo shows development week by week.
Crown/rump length and gestational age are closely compared with each other until around the end of the first trimester. When should I have my earliest scan? The ideal time for a sonographer to assess the gestational age in the first trimester is between to weeks of pregnancy.
This is the period which provides the most accurate assessment. Generally, ultrasounds which are performed in the first trimester are within 3-5 days of being accurate in terms of assessing gestational age. This is because although every little embryo is unique, there are still defining characteristics of development which apply to all embryos at particular stages of early gestational development.
As the embryo matures to a foetus, individual genetics and growth factors influence its growth. This is why an early pregnancy dating scan, rather than one done in the later stages of pregnancy, is considered more accurate when assessing the expected date of delivery.
With maturity, the size of the baby correlates less to its age than in the early weeks. How will my 7-week ultrasound be done? There are two ways of having a seven weeks ultrasound. One is via the abdomen – transabdominally and the other is through the vagina – transvaginally. Some sonographers believe that at seven weeks of gestation, transvaginal ultrasound provides the best and most accurate visualisation.
This is because the transducer does not need to send sound waves through multiple layers of muscle and tissue to “pick up” the returning images. When a transvaginal ultrasound is done at seven weeks gestation, the transducer is placed in the mother’s vagina and the sound waves are transmitted via her cervix and directly into the uterus.
- With this form of scan, it is not as necessary for the mother to have a full bladder.
- When having a transabdominal ultrasound, however, a full bladder is necessary in order to “lift” the uterus up and out of the pelvis so the embryo can be seen more clearly.
- Later, as the pregnancy progresses, a full bladder is not necessary as the enlarging uterus is no longer contained in the pelvic rim.
But I can’t see a thing! In very early pregnancy, the embryo and pregnancy sac may simply be too small to see very much at all. But with every day which passes, the embryo becomes bigger and more advanced in its development. A duration of only a week can make a significant difference in terms of what can and can’t be seen.
Am I having a boy or a girl? At seven weeks of gestation, it is still too early to (sex) the baby will be. It is also impossible to do a thorough foetal screening assessment because it is still just too premature in terms of embryonic development. However, general “mass” structures such as a head and body can generally be seen in the embryo at seven weeks.
In some respects, the seven-week ultrasound can be quite accurate because the embryo is developing very quickly. They are also not as mobile and active as they will be with future development. Thus, obtaining accurate measurements and visualising them clearly on the screen is a little easier than when they are able to do somersaults and move around a lot.
- Can I see my baby’s heartbeat at the seven weeks ultrasound? Yes, you should be able to.
- This is also more likely if you are having a transvaginal ultrasound.
- The average number of beats per minute (BPM) is between 90-110 BPM between 6-7 weeks of gestation.
- But by the time the baby has developed to full term, this rate increases to around 150-160 BPM.
One of the reasons for this is because the heart needs to work harder and more efficiently to pump oxygenated blood around its much larger body and brain. Will my seven weeks ultrasound be clear? The quality of the equipment and the skill of the sonographer are very important when doing any pregnancy ultrasound.
Like every other health professional, individual skill, expertise and training make a big difference to the outcome of their assessments. When you are first referred for a seven-week ultrasound, the first of many types of ultrasound, ask your GP or maternity care provider who has the best reputation for quality scan results.
How many ultrasound scans do you need during pregnancy? l Max Hospital, Pitampura
You may also like to ask your friends who have had a positive experience and to see who they would recommend in terms of having firsthand experience. When an ultrasound is done between weeks 12-22 of pregnancy, gestational weeks are considered as being within 10 days of accuracy.
- These ten days “window” of days either side of the estimated date of confinement – the EDC, is considered standard practice.
- Why wouldn’t my scan be 100% accurate? There are many reasons why not.
- Even with the best technology and most proficient sonographers available, ultrasounds do not provide absolute proof of dates, gender, size or the unborn baby’s status.
This applies at whatever stage of gestation the ultrasound is done. Because:
- The foetus may be stretched out, curled up, lying on its side or in a position which makes it difficult for the sonographer to fully estimate their size.
- Every foetus is an individual and influenced by their own genetic characteristics.
- The mother’s general obstetric health and the health of the placenta play important roles in the size of the foetus.
