first appointment questions

so i’m 16 and my first appointment is on tuesday i think i’m about 9 weeks 5 days. i’m wondering when i go to the DR, will they ask anything about the dad? like his date of birth or social security or anything or because we’re not married will they not ask anything?

we have been together for 11 months and i was just wondering as i don’t want him to be on the birth certificate until when/if we get married.
