Hcg levels

Is 584 for my hcg level good if I am 6 weeks? I honestly don’t know how far along I am. I could be 4,5,6 I guess. Period was the beginning of April, missed period the begging of May. Two peak days in between? Dr wants to go off of beginning of April. I had three sets of blood work so far, hcg was 14 then 48 now 584 all in a week. I wasn’t sure if that number was too low for 6 weeks or if I’m closer to 4/5 weeks. What does everyone think?
