I am 32 weeks pregnant. i have had about 12 or more ultrasounds. is this safe for my baby?

Yes: Hopefully, the ultrasounds were all performed for medically indicated reasons. However, ultrasound has been proven safe in fetal evaluations. In early pregnancy we take care to limit the amount of time an embryo/fetus is examined and adjust the power settings as low as possible. These are additional precautions to further improve the safety of a test already shown to be safe.
