Was anyone scared for pregnancy level blood works?

I had my first beta on Thursday 9/14 it was 145 at 9days past 5 day Pgs normal embryo transfer my doctor said that was a excellent start and I never had a beta that high this is my second pregnancy after a miscarriage in the other pregnancy my beta started low (73) and failed to double so I’m so scared for my results on 9/18. Im trying to be hopeful but I’m so worried!
