HCG Numbers

Hi all, I just had some questions about HCG and how it rises. I found out I’m expecting a few days ago and my first blood draw said my HCG was at 20. A little less than 48 hours later, it had gone up to 56. Now today(48 hrs later) it’s now at 130. I know they say it’s supposed to double every 48 hours but compared to the other people on here, it seems mine is staying lower. After so many losses, I worry this isn’t going up as high as it should in a healthy pregnancy.

Is this anything of concern?
