BFP, now what?! help?

So I just got my bfp a few days ago and I realized I'm at a total lost at what I'm supposed to do now. I went to the clinic and the doctors there gave me a referral to another doctor at an actual hospital. She hasn't called me back yet. I think I want to give birth at a birth centre though so how do I go about that and do I still go see this doctor? Ftm so I'm all confused, sorry if it's a silly question
