HCG numbers help!

Has anyone had HCG always double , except for one- it’s close but didn’t. I had a chemical back in march so my OB did 3 draws… then reached out to ask how I was feeling and said for my peace of mind she can do two more quants to make sure it’s still going in the right direction.

I have posted a few of my numbers once before but here they are again…

July 31- (two days before missed period) 24

August 2- 65.2

August 4- 169.2 

August 10- 4450

(Today) august 12- 8831.5

So from the 10th to today they didn’t quite double, the only time they haven’t. When I did all the tests from the 31-4 I made sure I did them at the same time (give or take 20 mins) I did todays an hour and 20 min sooner than the 48 hour mark.

Just looking for positive outcomes where numbers came close to doubling and the pregnancy was still ok.

Monday I would be 6weeks.
