GD and what that means for baby and i

hello, I'm 30 weeks pregnant recently I was diagnosed with "borderline Gestational Diabetes" I failed my 1 hour and my 3 hour i barely passed. I try to eat healthy but as does everyone I sometimes give in to my cravings. my doctor said the downside to this is having a larger baby. If that happens will i be induced earlier than 40 weeks? has anyone ever dealt with this ?
