A routine ultrasound between 18-20 weeks is performed to make sure your baby is growing as it should, confirm your estimated due date, and screen for fetal abnormalities. The ultrasound also evaluates the position of the placenta, checks for opening or shortening of the cervix, determines the amount of amniotic fluid, and verifies whether you are carrying one baby or more. Depending on the baby’s positioning at the time of the ultrasound, it is possible to confirm your baby’s sex at this time. It is important to remember that this is a medical examination, and visitors should be limited. Please call the office to review recommendations for ultrasound attendees. In many cases, women need only one ultrasound examination, but for a variety of medical reasons, your doctor may order additional scans during your pregnancy.
