Thank you so much for all of the good thoughts and well wishes! I was so nervous about seeing the baby again and all of your kind words definitely helped.
We went in for our second ultrasound early this morning. When the image showed up on the screen I couldn't see any flickering, but the doctor said "There's the heartbeat" and everyone was all "Ooooh". But I still couldn't see it (hey, I was sort of upside down) so he zoomed in and there it was. THEN I could breathe again and I finally felt relieved. Doctor said that everything is measuring just about right on track and the baby's heart rate was 186. That sounds really high, but the doctor said it's nice and strong.
So that was that. We got our cute little picture, I was told to stop talking all my supplements (Really? What if I'm not ready??), and they sent us on our way. I'm sad, but not that sad. Tomorrow morning I have my first appointment with the nurse at a new OB's office. I saw two different RE's and they both were very happy with my choice of doctor so hopefully I'll like this office too. And hopefully from here on out, I will be a perfectly normal and boring pregnant person.
