I had an ultrasound today. I got to see a tiny little baby ("it's still an embryo, dear") bouncing up and down, with her heart beating away just like it ought. Little head, little torso, tiny buds of arms and legs.
I'm still trying to wrap my mind around this. She is real, and she is the right size for her age, and all seems well. It is ok for me to fall in love with her, because it is likely that I will get to hold her in a few long months.
