Butterfly Wings

We had our doctor's appointment this morning and everything looks good!
We heard Baby B's hearbeat via doppler and it sounds like a butterfly's wings flapping; it's the coolest and most beautiful sound I've ever heard.
The doctor measured my uterus and said that Baby B is growing at a healthy rate. B is about the size of an avacado right now:
We were a bit disappointed when we scheduled our appointment with radiology; they
said that they only do the "anatomy ultrasounds" at 20 weeks. So, four more weeks to go (March 19) before we know if Baby B is a girl or a boy!
