5 weeks & first appt tomorrow

Elizabeth
Hi! I'm new here. I am 5 ish weeks along & go to the doc tomorrow (pretty lucky seeing as it was my scheduled yearly & I just found out I'm pregnant last night!). 
They don't know I'm pregnant yet. They think I'm just going for a pap. Will I be able to be treated like a prenatal check up? Or will I have to reschedule? 
Potential a dumb question. I am just so overwhelmed and excited and nervous and anxious to process and think clearly right now.
