Waiting and not waiting patiently

I'm sitting here on the couch, half-way listening to the TV and trying not to stare at the clock.  Only 35 more minutes until my husband will be home from work and we can drive the two hours necessary to meet with our RE.  I should be working, and I have managed to send a few emails, but mostly I'm just staring at the clock and googling really creative things like "what to expect at the first real appointment with a fertility specialist".  Argh.  I've been using OPK's the last several days, and I'm going to take another right before we leave for the appointment.  I should be ovulating today or tomorrow, so my husband and I have been baby dancing at all the right times, just in case and by some miracle we are able to get pregnant on our own this cycle.  But, it also just occurred to me that since I am so close to ovulation, could the RE possibly schedule me to have a follicular ultrasound study today?  I am so new to this world of fertility treatments, I don't know what to expect.  I am overwhelmed.  So overwhelmed.
