How to choose a doctor


Today i had my first prenatal appointment today. This is my first baby so I'm not sure what to expect. The whole appointment felt so rushed and it was hard to talk to the doctor. She told me that there are 6 doctors in the office that I will have to rotate through and I won't know which one will deliver my baby. I am 8 weeks and 3 days according to my last period. At my appointment they said I am to early for a heart beat and wont be able to let me hear it until 12 weeks. But everything I read and have heard says you can hear the heart beat by 6 weeks and usually get to hear it by 8 weeks. I had blood work done by my PCP at 4 weeks to confirm pregnancy.Is this a normal first visit experience or should I start looking for a new doctors office?
