More bloodwork and a date for the sonogram

So today my HCG levels was 4882 up from 2384 and I have my first ultra sound to listen for the heartbeat on January 13th at 11.  They will be able to tell me for certain whether it is indeed twins.  The nurse did tell she was surprised by how high my levels were and thinks it may be twins but we will know for certain soon enough.  I'm kind of getting used to the idea of twins.
