First OB Appt Not Until 9 Weeks

K8E
Hi First Trimesters! 
This is my first pregnancy and I'm currently 5 weeks 2 days. When I called my OB last week to tell them I got a positive at home pregnancy test, they said they don't do any tests until the first appointment- which isn't until I'll be 9 weeks 2 days. 
Is this normal? I feel like I might go crazy waiting that long!! Should I see if my PCP will do a blood test? 
Thanks in advance for any advice!
