Hcg not doubling anymore but still rising

Ally

I have a history of ectopic, going to do an early scan next week to rule out. Doctor said labs could be okay but since they aren’t doubling in 48 hours could be early miscarriage or ectopic given my history. Anyone have similar labs and it turn out okay?

12 dpo- 54

14 dpo- 142

16 dpo- 354

19 dpo- 889

23 dpo- 2583 (yesterday)

Doubling time progressively slowing down. Started off good but now much longer.
