Pre-natal appointment #2

I went in for another check-up with my doctor this morning. He said that I'm actually not as far along as we had originally calculated. According to the ultrasound I'm only 11 weeks pregnant as of today (we thought I'd be 13 weeks tomorrow.) So instead of being due November 17, I'm due December 1! How fun! Other than that, everything looks good and healthy, which is what's really important! I heard the heartbeat today, it sounded like a train! :]
