Pregnancy test ultrasound-Routine ultrasound – Pregnancy Info

A prenatal ultrasound is a safe and painless test that uses sound waves to make images that show the baby's shape and position. It can be done in the first, second, or third trimester, depending on what the health care provider is looking for. Women with high-risk pregnancies might have multiple ultrasounds during their pregnancy. Ultrasounds were once used only in high-risk pregnancies , but have become so common that they're often part of routine prenatal care. During an ultrasound, sound waves are bounced off the baby's bones and tissues to make an image showing the baby's shape and position in the uterus.

Researchers have mapped out the expected measurements for specific points in early pregnancy , so an early ultrasound scan can give a doctor some important information. For this purpose, an ultrasound is considered a highly accurate means of dating a pregnancy. In a normal pregnancy, the ultrasound results can provide an estimate of the gestational age to within five to seven days of accuracy. In the first trimester, doctors usually use a transvaginal rather than abdominal ultrasound to gather information about the pregnancy.

The transvaginal ultrasound provides the most accurate information in early pregnancy, given that the early developing gestational sac and fetal pole are extremely tiny at this point and a vaginal ultrasound can get closer to the developing pregnancy.

In a transvaginal ultrasound, the doctor or technician inserts a thin probe into the vagina in order to take a series of measurements, including the size of the gestational sac, the size of the yolk sac, the length of the fetal pole, and the heart rate. In an abdominal ultrasound, the woman will be asked to come to the scan with a full bladder, because this positions the uterus in a way that makes it easier to obtain measurements.

The doctor or technician then spreads a gel over the lower abdomen and uses a transceiver to take measurements from a number of angles. 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.

The results of an ultrasound are compared to what is expected for the gestational age of a pregnancy. The gestational age is calculated by the number of weeks since the last menstrual period; however, this method generally assumes a day cycle with ovulation occurring on the 14th day.

Many women have shorter or longer cycles and do not ovulate on the 14th day -- and this could affect what an ultrasound should show in the development of the pregnancy. For example, if a woman has a day menstrual cycle, she most likely ovulates around the 21st day of her menstrual cycle because ovulation usually occurs two weeks before the menstrual period would begin.

If the woman became pregnant and had an ultrasound scan six weeks from her last menstrual period date, her normally developing pregnancy would measure with a gestational age of five weeks, because the gestational age dating system assumes that she would have ovulated a week earlier than she did. If the woman did not know that she ovulated on the 21st day of her cycle, she might worry unnecessarily that she was having a miscarriage if she had an early ultrasound that showed only five weeks of development in her pregnancy when she was technical "six weeks pregnant.

Similarly, not everyone meticulously tracks the start of the menstrual period. If a woman cannot remember when her menstrual period started and guesses the wrong day, even if she does have a typical day cycle, this could also change the expected results of an ultrasound scan. Sometimes an ultrasound will give uncertain results. For example, if a woman is seven weeks pregnant and the ultrasound does not reveal a fetal heartbeat, the doctor may order another ultrasound in a week.

The pregnancy could still be normal but simply off by a few days in the dating—or the dating could be accurate but the timing is still within the margin of error for when the heartbeat becomes detectable on an ultrasound. Similarly, if an ultrasound reveals an empty gestational sac, this could still be a normal finding if the pregnancy is early along. The developing baby is too small to be seen on ultrasound until about five weeks of gestation.

In this case, the doctor may opt to repeat the ultrasound at a later date. In either of these cases, the ultrasound results may indicate a miscarriage or the pregnancy may still be normal. If the subsequent ultrasound shows that the pregnancy has continued developing, the earlier results can be attributed to problems with dating.

If the subsequent ultrasound still shows abnormal development, the doctor can conclusively diagnose a miscarriage—but the doctor cannot determine the result based only on one early pregnancy ultrasound scan in many cases. The wait for the repeated ultrasound can be emotionally very difficult, but it may be necessary in order to avoid a misdiagnosis unless other information is present to help the doctor interpret the ultrasound results.

If there is any question as to whether or not a woman is having a miscarriage based on an ultrasound scan, the usual course of action is that the doctor will order another ultrasound in a few days or a week. Sometimes, however, the presence of other diagnostic information can help a doctor to interpret ultrasound results even if there is only one ultrasound scan.

For example, if a woman has a positive pregnancy test the day of her missed period followed by confirmation with hCG blood test results and an ultrasound four weeks later shows a pregnancy at only five weeks gestational age, the doctor may conclude that the woman has had a missed miscarriage—because the positive pregnancy test a month earlier would indicate that the pregnancy should be more developed. The American Pregnancy Association cites the guideline that if the gestational sac is larger than millimeters and contains no fetal pole or if the fetal pole is larger than 5 millimeters and has no heartbeat, miscarriage has occurred.

These situations would be called a blighted ovum or missed miscarriage , respectively. As the pregnancy progresses, ultrasound becomes more and more accurate for determining the viability of a pregnancy. If an ultrasound in the second or third trimester shows that a baby has no heartbeat, this is considered conclusive for diagnosing a missed miscarriage or impending stillbirth.

Ultrasound During Pregnancy - Everything You Need To Know About Baby Ultrasounds

The results of ultrasound testing provide you and your health care provider with critical information about you and your baby. See below for descriptions of the information gathered from these two types of ultrasounds. Ultrasound uses high-frequency sound waves to create images of the inside of the body. The technique does not use any radiation.

It is safe, painless and relatively quick test that usually takes around 30 minutes. The technician will put a warm gel on your abdomen and use a scanning device to get the ultrasound images. Sometimes the ultrasound must be done through the vagina; this procedure may be uncomfortable, but is not considered painful.

Ultrasound is not used to diagnose pregnancy, but is used to date a pregnancy and assess numerous health aspects of the fetus and mother. A dating ultrasound gives an accurate estimate of how far along you are in your pregnancy. Many women are uncertain of exactly when conception happened. Ultrasound can tell you how many weeks pregnant you are, based on the size of your fetus.

This generally predicts the expected date of birth within 5 days. Knowing where you are in your pregnancy is important for your prenatal care, all the way from your first trimester, through to labour.

This ultrasound is usually offered in the second trimester, between 18 and 22 weeks of gestation. The number of fetuses, gestational age, and location of the placenta will be assessed. The ultrasonographer will take many measurements of your baby to screen for any abnormalities.

The position of your placenta and the vessels in the umbilical cord will be examined. If you are at high risk for fetal abnormalities, anatomic ultrasound can be performed during early pregnancy weeks. We use cookies to improve functionality and performance.
