Most healthy, low-risk pregnancies typically involve about 2 to 3 ultrasound scans throughout the pregnancy. Typical ultrasound schedule:
- First ultrasound: Usually done between 6 to 12 weeks to confirm the pregnancy, check the heartbeat, estimate due date, and verify the baby’s location in the uterus.
- Second ultrasound (Anatomy scan): Performed around 18 to 22 weeks to examine the baby's anatomy, check for abnormalities, determine sex if desired, and assess placenta and amniotic fluid.
- Third ultrasound (if needed): Sometimes done in the third trimester to check the baby’s position, placenta location, and amniotic fluid, especially in high-risk pregnancies or if complications arise.
Additional ultrasounds may be necessary if there are concerns such as multiple pregnancies, medical conditions (e.g., diabetes, hypertension), or if previous scans show abnormalities
. In summary, while 2 ultrasounds are standard for most pregnancies, the number can increase based on individual health factors and pregnancy progression
