I agree with the PP. GD shouldn't be the reason for induction if your GD is well controlled and your baby isn't at risk of macrosomia. I would ask for extra monitoring and wait until 40 weeks before you discuss induction.

I had GD with #1 and Went into labour naturally at 39 weeks 2 days and had a normal sized baby. My GD was controlled with diet and exercise so there was no need to even discuss induction. I would refuse it unless your OB can give you a good reason why..

Good luck hun!!
