OB referral for Tricare ??

Tracy • Expecting baby #1! 2/2/2020 🤰🏼

I went to the hospital yesterday for blood pregnancy test to confirm, and I am. They said they would refer me to an OB in town since they don’t have one on base. They said I can request a certain doctor I want which I did then they referred me to someone else over an hour away. I want to know if I need to call tricare to ask them personally to give me this doctor? I am so confused there’s a million different phone numbers online and I have no clue who to call.
