6w 3 d to early?

Is 6w 3d to early for my first prenatal appt?... my original appt date was schedule for August 12, back in June- it was the first date available... the scheduler told me she would put me on a waitlist list in case some cancels... well there has been a few cancellations, but i was never fast enough until last night, an appt became available for tomorrow... i grabbed it trying to be the first one... Didnt really realize it would mean, me going in at 6w 3d. What can they tell me so early on... i know the heart beat is usually not there until 8 weeks.. so what would an ultrasound show?
