Induction

I’m 33 weeks and I just got bumped up to 1000mg of Metformin a day. I have an appointment with my OB tomorrow and I was wondering if it would be too early to ask about a planned induction? I read they induce women with GD around 37-39 weeks. I’m just curious about what my doctor has planned and would really like to know if he wants to induce me. Has anyone asked their doctor to plan that far ahead?
