Prenatal , OBGYN Care Question

So my last appointment was Nov. 6 & before going in for my ultrasound & dr visit St. Jude called me to inform me they looked over my insurance that just recently changed from straight medi-cal to health net medi-cal & told me they can no longer see me because they don’t accept health net & also because I live in LA county, not OC. But I had been going there getting prenatal care since August. I have been assigned a new doctor and all that but haven’t made an appointment because my new doctor isn’t exactly an OBGYN which is what I need. I have placenta previa & Nov 6 was an appointment to see if it has moved. I’m 35 weeks pregnant and don’t know what to do. Well setting up an appointment would be something but not sure how to go about it... I would like to go see an OBGYN ASAP, like walk-ins available soon. Any suggestions on where I can go? An OBGYN that takes health net medi-cal ...
