Having had GD with both of my babies I can tell you that it's highly likely that you'll encounter pretty strong pressure to induce. Even if they decide your bubs size isn't an issue, they'll still want to do it around 39 weeks because they get antsy about plancental deterioration which is apparently slightly more likely in GD pregnancies (this is debatable).

My best advice to you would be to research, research, research. You don't have a lot of time but I can tell you from my own research that the whole GD thing is very shady science. For every study that says one thing, you can very easily find another that will outright contradict it. Even the tests they use to determine if you have it are questionable.

No one can force you to do anything, and your well within your rights also to ask for frequent monitoring at the end rather than induction. This way as long as bub is doing ok you might be left alone.

The pressure is strong and unless you've done your research and are confident in your decision making it's really, really hard. I've heard of many mums with GD who were told their babies would die if they refused induction - complete rubbish but because they're so vulnerable it's so hard to get the facts.

Good luck with it all, just remember this is your labour and birth and baby and ultimately it is your decision, even if your made to feel like it's not
