Newly preggo

I just found out I'm pregnant and my husband and I don't want to tell anyone right away. So instead of going to my mother for advice I'm asking on here! I'm trying to decide if I should first go to my primary care doctor (probably give a urine sample and confirm pregnancy) and then have him recommend an OB doctor or if we should just pick an OB doctor and start out there. Glow says I am 5 weeks. Thank you in advanced!
