I went to one for my 20wk ultrasound and I will go for another ultrasound in a couple wks. It was just like my regular dr really. He did an ultrasound, said everything looked great and I was on my way. I only went bc I am 35 so my insurance covered being seen by both my dr and a high rish OB. I think you will find it is just like going to a regular OB, they are just more skilled at finding things, but likely things are fine so it will be a non-event.
