how to make an appointment ?

hey guys ! so I have a silly question . I have never had an actual gyno, we have a local health clnic and I have always went there for check ups as that's just where I got my birth control. so now that i have 2 positive home pregnancy tests how do I go about finding a doctor? do I just call and ask to make an appointment ? tell them I'm pregnant ? I can't ask anyone for advice because i want reassurance everything is okay before spilling the news :) TIA
