Wanting some input

I am currents 6 weeks with our rainbow baby and have quite an extensive medical history. I am posting because I am currently having issues with kidney stones. I called my OB and they are wanting to see me tomorrow for an office visit. I have an appointment for my first ultrasound in 2 weeks. So my question is this, have any of you ladies been to the ob where you don’t have an ultrasound on your first appointment? Thank you for reading.
