Got my BFP!

After 6 months of trying my husband and I finally got our BFP! This may be a dumb question to most, but I am honestly clueless. My last pregnancy my husband was still in the military so I have a feeling things were a little different. All I had to do was go to the Naval Hospital, tell them I had a positive test at home and they did a test right there. If it came back positive they would call and set up an appointment with the OB’s there. Now that he’s out, I don’t even know where to start. I don’t have a doctor. How long do I wait to call one and get the process started? How long usually until the first appointment? What happens at the first appointment? Someone please help!
