Seeing my baby's 'house' for the first time

Today was my first visit to the OB-GYN. I lucked out because I have a lady doctor, and I didn't even ask for one! It was a pretty uneventful visit, just alot of forms to fill out, blood tests, urine samples. I was hoping to be able to hear the heartbeat today, but at 7 weeks, it is still too early. My doctor did manage to hook up the ultrasound machine to see if we could detect anything. I searched in vain and was unsuccessful, but at least we could see the pregnancy sac as clear as day! It was pretty neat, it looked like just a little baggy floating around inside of me. Even though I couldn't see my little one in there yet, it made me smile to think of that sac as being my baby's 'home' for the next 9 months. I am sooo looking forward to the day where we will be able to hear the heartbeat for the first time! We will be telling our families about this soon. We are already busting at the seams to tell them, but we decided to wait until Chinese New Year's weekend.
