Update

Woops! Sorry it's taken me so long to post about the appointment...

Everything went well. The appointment was more like an "orientation" to being pregnant, where we sat in an office-like room and went over family histories, things I should and should not be doing, etc.
We scheduled an ultrasound for October 9th, and my first "real" appointment for October 10th. We won't be able to tell gender from this ultrasound, as it's still too early, but we'll be able to check in and make sure everything is looking good. They'll measure the baby and see if my due-date needs to be changed, and also check to make sure there's only one little bugger in there!
