The dates are 10dp5dt and 14dp5dt, which are in the normal range for both twins and singletons at betabase.info. BTW, if you don't obsess ove the numbers at betabase.info when figuring out how your numbers compare to others, you should.
The doubling rate is about 43 hours, which is good, although not great. 40 hours would be "great."
In any case, I voting on a very strong singleton in there. I don't think there are two little ones making a home any more, although I did after the first numbers came in.
I have to be honest that I don't feel out of the woods yet. I know this is a whole new ball game with fresher eggs. Nonetheless, after a bazillion miscarriages, I'm just not sure when I'm ever going to feel "safe" and "pregnant." The only time I felt that way was the first pregnancy, when I was too stupid to know any better.
