I'm 33 weeks and went in to my new ob on Friday and had the one hour glucose drink test,  when the time was up they said I failed and I heard the nurse say the result was 157. They rescheduled me for another 3-4 hour test on Wednesday. Should I be worried? I've tried my best to stay healthy and avoid this. Also many women in my family have had gestational diabetes during pregnancy so can that effect me?
