Petals, I also had insulin controlled GD. I wasn't happy with induction at 38 weeks so I agreed to go to the hospital every second day for 30 minutes of CTG monitoring. In the end I was induced at 39+4 weeks, but was already 3cm dilated and started having contractions after the cervidil strip (gel alternative) was placed.

How are your blood sugar levels? I firmly believe that if you are controlling your BSL's, either with diet or insulin, then there is no need to induce. I am constantly disappointed in myself for agreeing to the induction when I knew that it wasn't needed. I would have had a far better chance at having a good birth experience if I had waited for natural labour but found it really hard to stand up for myself around the doctors.

As for induction resulting in C-section, that just depends on how ready your body is, how you react to the drugs and how bubby copes on the day.

Good luck
