OneMedical users?

I'm getting irritated with using OneMedical. I got a positive HPT yesterday and so I called my doctor's office today to set up an appointment. I was told that they don't do a blood test, only a urine test to confirm, and that if I use their prenatal services, I have to deliver at a teaching hospital and my OBGYN/care providers would not be present.
I pay a yearly membership and have taken a lot of time to find my primary care doctor using the OneMedical service but their rules for prenatal care are so absurd to me! 
does anyone have any experience using OneMedical and their prenatal system?
