Ultrasound is a standard tool in obstetrics care. It uses sound waves to create images of your baby, and it does not use radiation. You may need ultrasound testing at several points during pregnancy, and while each scan serves a distinct purpose, together they help your provider track development from start to finish.
Confirmation of Pregnancy
Your first ultrasound often occurs at an early prenatal visit. It confirms the pregnancy and checks that the embryo has implanted in the right location. Your provider evaluates your uterus during this visit for any structural factors that may affect your pregnancy. If you received infertility care, the scan can verify that treatment led to a viable pregnancy and confirm whether you are carrying more than one baby. Knowing this early helps your provider plan the right level of obstetrics support for you. Early imaging establishes a clear baseline for the months ahead, so this gives both you and your provider a starting point for all future care decisions.
Assessment of Anatomy
A mid-pregnancy scan usually takes place between weeks 18 and 22. It is one of the most comprehensive scans you will have. The technician carefully checks that each structure has formed correctly. If anything requires a closer look, your provider may schedule a follow-up scan or refer you to a specialist. This information guides the rest of your obstetrics care, and it helps your provider prepare for delivery. This scan reviews several key areas of your baby’s development:
- Brain, heart, spine, kidneys, and limbs: Each structure is examined for correct formation.
- Placenta location: The position is checked, as it affects how your provider manages your pregnancy.
- Amniotic fluid levels: Fluid volume is measured to assess your baby’s environment.
- Baby’s sex: Your provider can determine the sex at this stage, if you choose to find out.
Measurement of Growth
They measure size and position, and they give your provider a clearer picture of development. Later ultrasounds track how your baby grows over time. When results fall outside those ranges, your provider may order more scans to gather information. Low or high fluid levels can signal a need for closer monitoring. Placental position is reviewed as well, since changes in location can affect delivery planning. Your baby’s position in the uterus becomes more relevant in the final weeks.
Ultrasound helps confirm whether your baby is head-down or in a breech position before labor begins. If your baby’s growth slows or stops progressing as expected, your provider can adjust your care plan based on that data. This ongoing monitoring supports timely decisions, and it helps your provider respond to changes before they become complications. Repeat scans are a practical and reliable way to stay informed throughout the later stages of pregnancy.
