SHAME ON ME!
I should have posted before now - that was rude of me to say I was having an ultrasound yesterday and then let a whole day go by without posting the results. Here he/she is:
2nd ultrasound - all is well!
Gorgeous, huh? The head is on the lower left, and you can see the little arm buds just above (he is upside-down!) Currently measuring 19mm and the heartrate is 184bpm. Perfect, perfect!
Me? I am still horribly sick. But after seeing this little person, it is easier to deal with for sure.
