Scheduling to be induced

I have GD and my OB has been talking about scheduling me to be induced.  I am 36 weeks Friday and have an ultrasound with Maternal Fetal medicine.  My last one at 32 weeks he was 4 lbs 11 oz, they said he was at the 64 percentile.  I have kept my sugars under control on a strict diet and night time insulin.  If he is In the normal size range I don't see why I would have to be induced early.... I'd like to go as natural as possible.
