nervous about tomorrow

somehow i have been calm through the 2ww.   maybe because not knowing means there is a chance i am preggers.
tomorrow is my first beta test and i am getting nervous.  i have "symptoms" that are most likely just "side effects" of the progesterone in oil shots:  hearburn, some cramping yesterday, sore boobs, etc.
we transferred 2 Grade A blastocysts on day 5.  now i am 10dp5dt.  the dr did two u/s to check the lining and bw to check my levels and everything looks good.  there is no reason to think this didn't work, but there is always that chance. 
so i am trying to stay calm, but am wondering how i am going to sleep tonight ;-)
