Just a quick update. We had our first ultrasound today, and so far, we have a healthy little baby in there!  It was very very tiny but had a strong heartbeat that we could see flickering away on the monitor. We are measuring exactly where we are supposed to be and the baby is implanted in a good spot.  So far, so good. And we are just praying it stays that way.  I know we are nowhere out of the woods yet, but I'm going to let the memory of that flickering heartbeat keep me hopeful.
