First time mom and worried .!!!

Well I got my first BFP on July 4th . And went in for my first blood work on the 11th at 4 weeks 6 days HCG levels came back as 535 . Nurse wanted me to go back again to see if it rises. Due to me ovulating really late July 21st confirmed from temping and opk she said it was low due to me being very early . I went back July 17 at 5 weeks and 5 days with HCG levels at 3,305 and progesterone levels 26.5 . She said my progesterone was good BUT still thinks my HCG levels should still be higher . She ordered me for a early Scan which was suppose to yesterday but when I went to the appointment come to find out she never put in the order and of course her office was closed . So now I have to wait until after vacation to get in for a scan and I'm just worried that something isn't right . When I saw my numbers I was happy until she told me SHE thought it would be higher and stressed me out . Should I be worried that I have to get a early scan .? And is my numbers that bad .? First time being pregnant and all this numbers and levels is new to me .! 🤷🏽‍♀️🤦🏽‍♀️
