Big day tomorrow

Tomorrow is a big day for us! The first ultrasound, we should be able to see a heart beat or two.  Ash is really scared. There is always talk of surrogates going in and there not being a heart beat. She had some cramping today so she's worried.  I don't know how to comfort her or ease her mind. I can show her statistics until we're both blue in the face but there is still the chance that tomorrow could be heart breaking. In my heart, I feel that everything is fine, that there is 1 little bean (ok, I know the odds are against us, but I really think two) and the heart beats will be strong and growth will be exactly where it should be.   I guess all I can do is wait until tomorrow and she'll see herself that all is well.
