Hcg levels

Hey this is my first pregnancy! I can’t get in to see the OB/GYN until I’m atleast 8 weeks (October 4th can’t come soon enough) and I was gonna go to my primary care clinic and have them confirm the pregnancy/test HCg levels! I was wondering what normal HCG levels should be at 5 weeks! I’ll be 5 weeks and one day tomorrow! Also I tested positive on the day of my expected period? Is that any clue on how high my HCG levels should be right now? I used clear blue digital to test. Any feedback/advice is welcome!
