Okay I got the call, so my hcg went up to 749, here are my levels:
12dpo 21
14dpo 60
20dpo 749
So my doubling time for the last 6 days is just under 40hrs, the nurse seemed happy with that.
I asked if I could be optimistic and she said YES, that my numbers are rising at the correct rate and that's all they look for now.
I am being book for an ultra sound Nov 24, and I'll be 7 weeks.
