HCG Levels??

Hi.. i’m 17 & this is my first pregnancy.. i just wanted some opinions/advice please?

On Friday morning i got a faint positive on a hpt so i done a blood test that same morning which showed my HCG level was 15.. the doctor asked me to come back on Monday (3 days later) for another blood test which showed my HCG level as 165 then i went for another blood test today (3 days later) and my HCG level is 585.. Ive had one doctor tell me it’s bad that my levels should be over 2000 and that it’s probably an ectopic pregnancy, then another doctor tell me it’s good and my levels are rising perfectly - based off my last period i would be 4 weeks and 5 days today!

What does everyone think? Do my levels sound normal? Has anyone had levels similar to mine and also been 4w+5d & ended up having a healthy pregnancy? (i’m not experiencing any ectopic pregnancy symptoms - except for the rare few cramps in my stomach which just feel like period cramps and aren’t that bad).
