I got a call back within a week of our NT, and yes they gave me my odds. However, the doctor was very clear that those results would be also averaged WITH the results from the 2nd part of the test, done during our anatomy scan, and that's when they give you the final numbers. Maybe that's why you felt she was being vague, because the test isn't really done yet.
That being said, if you feel you're not getting answers from your doctor, or that they are unclear and you feel uncomfortable, I might start looking for a new caregiver. IMO a huge part of that relationship is feeling confident and at ease, and that I wouldn't want someone guiding me through labor and delivery who I didn't trust 100%.
