At my last blood draw my OB said my levels were 13. They said the same thing. "The numbers have come down nicely." I don't know what a full miscarriage work up is...
If I were you, I'd call and ask what tests are regularly done and why...Tell them you're worried. Maybe they can fill you in so you don't have to worry about the appointment on Monday. Or, ask if the doc can call you. That way you can get your answers.
By the way, totally off topic, but, I love your Cullen stuff!!!

I love the Twilight series!!!
Keep me posted. I'd like to know what the doc's office says.
