Elective Ultrasounds?

Ma

A coworker I trust has a pregnant daughter, and they did an elective gender reveal ultrasound. The place is highly rated, they have all of their people certified, and it has 219 reviews and all of them are 5 stars.

Still, I keep reading that it could be unsafe for various reasons.

I wanted to go to my regular 20 week appointment but go for an elective ultrasound the following week when my mom is able to fly down.

Has anyone else done anything like this? Any advice?
