Concerned about doubling time...help!

Jessica

Can you post your doubling times? I worry mine has slowed down too much...

16dpo - 143

19dpo - 467

25dpo - 3398

I'm 6 weeks today (28dpo). Between 16 and 19dpo doubling time was 35.1 hours but now it's 49.2 hours. Did anyone have similar numbers and everything turned out ok?
