Doctor's Appt today

So I went to the doctor today to get my results from my blood test on Monday.  My HCG number last Wednesday was 20, and it is supposed to at least double every 48 hours.  On Monday then my number should have been at least 120 and my actual HCG levels were 307!  That means my numbers have been doubling at a rate of about 30 hours.  All good signs!  The doctor said that everything looks great and he set us up for our first ultrasound in 3 weeks.  So we will get to see our little bean on January 28th at 4:00 pm!  Yeah!!
