Just thought I'd share my experience with you too. Like
@kitty55, I wanted to know evidence behind inductions at 38 weeks. I asked my consultant about this and even she struggled to find any up to date evidence! We agreed that I would be induced if I had symptoms that merited it and not merely just because I was diabetic.
Unfortunately my 36 week growth scan showed the baby had grown more than expected and my amniotic fluid had increased in volume. Even at this stage my consultant agreed just to monitor and scan again the following week. I spent that night struggling with low blood sugars, I had a lot of lucozade and little insulin and that only just kept the hypos at bay.
My consultant made the decision the following day to induce me, she admitted herself, this was as much based on gut feeling as it was evidence. I was given steroids over a 24 hour period then started the induction process. I only required the first pessary and that started me dilating. They then broke my waters and from there on my labour progressed with out any further intervention required. I had a healthy baby girl born at 36 + 4 and 48 hours after the induction was started and weighing 7lbs 5. She had no problems with her breathing. She required a short time in neonatal to treat jaundice but this resolved quickly.
Hope your pregnancy is going well and all the best with the labor. Just remember your body is designed to do this and it can do it!!
