Fetal ultrasound. Ultrasound pregnancy. Join now to personalize. A pregnancy ultrasound uses sound waves to create images of your baby. You may have your first ultrasound early in pregnancy a first-trimester ultrasound or you may have a standard ultrasound at 18 to 22 weeks. Pregnancy ultrasound allows your provider to check on your baby's health and development, monitor your pregnancy, and look for any physical abnormalities.
It's also used for some genetic tests, and to make sure your baby is doing well in late pregnancy. What is ultrasound? When do you get your first ultrasound? What happens during a pregnancy ultrasound? Why do I need a pregnancy ultrasound? How long does an ultrasound take? How many ultrasounds will I have during pregnancy? Next to delivery, ultrasound scans are one of the most anticipated milestones of a pregnancy.
For many, seeing that black-and-white blob is the moment their impending parenthood starts to feel real. But how many ultrasounds will you get over the next nine months? And is there such a thing as too many? Ultrasound technicians create an image of your baby by pointing sound waves at soft tissues in your body using a handheld probe that is either inserted into your vagina or a transducer that is rubbed over your belly.
The waves that bounce back are translated into a picture by the imaging technology. Midwives and doctors use those images to monitor things like how the baby is growing or to look at the health of the uterus, says Jasmin Tecson, a registered midwife who has been practising for almost 13 years with Sages-Femmes Rouge Valley Midwives in Scarborough, Ont. This may be done separately or at the same time as a scan offered at weeks as part of the optional screening for trisomy 21 or Down syndrome.
Some doctors may order a routine growth scan in the third trimester, but that depends on the pregnancy, says Berger. Wondering when is the first ultrasound? The answer varies for everyone. Wear two-piece clothing to your ultrasound, to allow for easy access to your tummy. At some high-tech centers, doctors use 3-D ultrasound to provide pictures of the baby with photograph-quality details.
High-tech centers may use this type of ultrasound to better evaluate a baby's growth and development , as well as detect facial abnormalities or neural tube defects. If you have certain pregnancy complications, this type of exam may be recommended.

Because there are so many things to look for, this ultrasound will take at least 45 minutes—if your little one cooperates! During the full anatomy, week ultrasound, you can find out if your baby is male or female. When the scan is complete, Meriter will even send you a link to view some fun photos of your baby! 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.
In the meantime, you can enjoy those 2D or 3D photos of your baby! Sometimes, women need additional ultrasounds during pregnancy. 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. These ultrasounds take less time than the full basic anatomy ultrasound because there are fewer measurements required. 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.
To an untrained eye, they can look pretty fuzzy or obscure. These pictures show facial features and look much more baby-like than the kind of obscure 2D images.
