We had our 8.5 week ultrasound today. We got to hear our bean's heartbeat and see his/her brain (the black spot in the baby's head isn't airheadedness but huge brainage), head, spinal column, and arm and leg buds. Heart rate and size are all good. fyi -- the small sac in the upper left hand corner is a hormone sac that takes care of our bean until my placenta kicks in (~ 12 weeks).
Our ultrasound tech (who has 4 kids) describe our bean's size/shape as similar to a Teddy-graham. DH now imagines our baby as a mini-bear cooked to a golden crispy brown, which is so cute.
Here's the pic of our little Teddy-graham. The arrows point (from top down) to head, arm bud, and leg bud:
