The Baby is measuring right on for 16 weeks, and currently weighs 4 oz. My blood pressure is still doing well, and the doctor didn't seem at all concerned about it at this time.
The next ultrasound will be in a month, at 20 weeks, and (if Baby is feeling cooperative) we might be able to find out if it's a boy or girl at that time. And, hopefully, we'll be able to see more on the 4-D ultrasound then as well.
Here are a few pictures from today's ultrasound:

Laying face up, here is the Baby's face profile

Here, the Baby is laying face down, and you can see the head and body (the spine is VERY visible)

Admittedly, this one is a little scary-looking. The Baby is facing us in this picture, and because s/he doesn't have much body fat yet, the face looks a bit skeletal (or alien-like).

Here's the back of the Baby's head and back (you can also see his/her left arm and hand) in 3-D
