So, I'm a terribly inpatient patient. I looked at my RE's online portal to see if by chance my third beta number had posted. I really didn't think it'd be there, but it was. They are closed this weekend, so I won't get a call until Monday. Anyway, my beta doubling time significantly slowed:

12 dpo: 34
14 dpo: 99 (doubling time of 33 hours based on draw times)
16 dpo: 155 (doubling time of 74 hours based on draw times)

It doesn't look like I should be too optimistic, but DH is. He looks at it like if I didn't get the second beta done, then doubling time would be 45 hours. I really don't think it works that way.

Anyway, I can't find anything on the rate slowing this drastically this early, so I'd thought I'd ask. Has anyone experienced this? If so, what was the outcome?
