PHS SILENT ULTRASOUND

mommy2be

I had an ultrasound today I am 33 weeks pregnant and it was labeled as PHS SILENT ULTRASOUND, what does that mean? They said everything looked fine and that they would send this to my normal obgyn. I got the ultrasound done at a high risk clinic that I’m going to for diabetics. That label freaks me out, anyone know what it means???
