what to do now?

This is my first pregnancy. Mine an his parents don't know yet. I'm 5 weeks and 1 day today. I went to the hope pregnancy center today an they confirmed I am pregnant and set a ultrasound for October 4th. Should I just wait until then to see what happens or call my family dr and set up my first prenatal appointment? I seen and read so much on those an don't like dr's as it is so I am scared to go the dr. Since they put me through so much testing.
