If you're pregnant with your first child, you can expect to undergo quite a few tests over the next nine months. Some of those tests will require you to have blood drawn while other tests will require you to leave urine samples. Then there are the ultrasound scans that you'll receive. Ultrasound scans are a painless procedure that's used to monitor your progress during pregnancy. There are many reasons why an ultrasound scan might be necessary during your pregnancy. Here are four reasons why your doctor might schedule you for an ultrasound. 

Initial Ultrasound Scan

Now that you're pregnant, your doctor will schedule you for your initial ultrasound. This ultrasound will usually occur sometime after 12-14 weeks of pregnancy. During this ultrasound scan, your doctor will be looking for information, such as your due date and the condition of your uterus. They'll also be checking for the presence of multiple babies, as well as for any genetic abnormalities. In most instances, the doctor may be able to determine gender during this initial ultrasound scan. 

Anatomical Study

During your pregnancy, your doctor will want to monitor you for various factors, which is why you'll have a second ultrasound sometime between your 18th and 20th weeks of pregnancy. This scan is intended to provide the doctor with a more detailed anatomical study of the baby. However, it also provides a more detailed study of your placenta and uterus. Also, if the doctor was unable to determine gender during the initial ultrasound scan, they'll attempt to obtain that information during the second scan. 

Gender Reveal

There are instances where the first two ultrasounds are unable to determine the gender of the baby. When that happens, you can schedule an optional third ultrasound scan. This is often the time when parents choose to receive a 3D or 4D ultrasound scan. These ultrasound scans allow you to enjoy a more detailed glimpse of your baby prior to their birth. This is also a good way to learn the gender and to receive a keepsake video of the scan. 

Complications

Finally, while you're pregnant, the doctor will watch for potential complications. If any arise, the doctor may order an additional ultrasound scan. This scan will be used to identify complications that need to be addressed right away. Some of those complications include bleeding, preterm cramping, and fetal distress. There are also times when the doctor will order an additional ultrasound to monitor the size and position of the baby.
