Today's number at 19 dpo (14dp5dt) was 2962. It more than doubled twice from the last beta at 15 dpo. I have to be honest with you: I know that's a fine number, but I'm a little disappointed. I'm not worried, but I'm not longer convinced that it's twins. It may be that there were twins and now there isn't.
The doubling rate was 43 hours, which is a little bit longer than the average of what they see on Betabase.info for either singletons or twins. I know the doctors are happy to see any doubling rate less than 48 hours. But that is sort of like saying that seeing a heartbeat (any heartbeat) reduces the miscarriage rate to 5%. It doesn't.
And maybe it's with my miscarriage rate that it's just not likely I'm going to be thrilled with anything until I have a baby in my arms. It's a fine number. I would have liked something closer to 3200. I can't have everything, eh?!
