ob visits

hi!  i'm 18 weeks pregnant.  i'm seeing an OB and a perinatologist because of high risk pregnant.  i don't know if i receive good enough care because my peri doesn't give me ultrasound on his own.  his sonographer gave me ultrasound on every appointment.  On the other hand, my OB never gave me an ultrasound.  i only had one from the nurse practitioner on my first ob visit.  i have received many treatments before getting to this stage.  i just want to know if I'm in good hand. or is it a common practice for them during pregnancy visit?  appreciate for any feedback.
