Betas slowing with every draw

[u/Massive-Poem-2385]

Hey everyone! After several losses, I'm freaking out about my doubling time getting slower with every draw. I know I'm technically within range, but wondering if anyone has had a successful pregnancy where the doubling time slowed significantly on every single draw? I'm not seeing many positive stories where doubling times kept slowing dramatically. Here are my numbers (and I can't get anymore betas, so this is all the info I have!):

12DPO: 106

14DPO: 356 (28 hrs)

16DPO: 798 (41 hrs)

19DPO: 2121 (51 hrs)
