Gestational diabetes and induction

Catherine • First time mommy here, due with a sweet little boy named Ben on March 26, 2016.
One of my friends told me that if you have gestational diabetes, they will induce you at 39 weeks? I'm going to be 35 weeks tomorrow so I'm not sure what to expect? I have gestational diabetes and I'm just wondering what to expect. Like I said earlier, my doctors all suck and don't tell me anything. Any help will be super appreciated.
