HcG levels??

Curious what other moms got the first time they had their hcg checked? I had bloodwork yesterday at 5w4d and the doctor just called to say it was 7,602. Doctor said that's good, looks normal. Based on what I could find online that looks normal, with the range being so different on different sites. 
One website said 18-7340 for 5 weeks and another said for my exact day, 7220-17050.
