First appointment. Help.

So got my BFP then went to the health clinic. They did a pee test then said I come back the 30th for an appointment. I will be 6 weeks when that happens. I just don’t know whether to tell my bf if he needs to leave work that day cause it will a ultrasound or it would be just turning in WIC papers that they gave me and told me to have them filled out when I come back.
