Insurance and Hospital Contract Expiring

So I am pregnant and we have been getting care by a doctor that is under a group of doctors (really big group more like a hospital). I was told that our insurance (BCBS) is not renewing the contract with them for the new year. There may be continuity of care the doctor group said but we have not gotten anything from Blue Cross. We love our doctor, is there a chance we can keep them by continuity of care until birth?
