Betas not looking great

Hi all, I have a history of early losses and my hcg hasnt gotten above 35 with my last two chemicals.

Here are my recent blood draws for this pregnancy:

10 DPO —> 12

12 DPO —> 56.3

14 DPO —> 86.2

Any success stories with similar doubling times? I have a knot in my stomach. I feel devastated after my last draw.
