In my first pregnany I had my glucose test done in the late afternoon, so i ate as normal all day but then didnt eat anything in the last couple hours before the test.

This time around I have it scheduled for late morning. The assistant in my OB's office told me not to eat an hour before my appointment, but then when I called to verify, a different person told me not to eat anything from midnight the night before. That doesnt add up to me. I'll be starving ifI wake up and have to wait til my blood is taken around noon to eat.
Did any of you experience this fasting?
