I finally got my numbers from last week.
Monday's test came back at 18,309 and Thursday was 36,424. I was a little concerned that they didn't double in exactly 48-72 hours, but the nurse told me that after week 6 or if the numbers are above 13,000, they do take up to 4 days to completely double. Thankfully mine doubled in just over 3 days (3.02 to be exact).
So I go to see my ob next Wednesday and hopefully get an appt. for an u/s. I want to make sure this little bean is right where he's supposed to be.
