What to expect at your anatomy scan

Your OB or midwife will schedule your anatomy scan between 19 and 21 weeks to see how your baby’s organs are developing. Ultrasounds are safe for checking growth and development; they use water and sound, and there is no radiation exposure. You can request to find out the baby’s sex, which is reported to your doctor or midwife. The sonogram also can let you know where your placenta is located.
