Anyone with gestational diabetes deliver a healthy baby?

I am due any day now (39 weeks) but I do still get spikes because of poor diet. I have mostly good numbers for most of my meals and throughout each day, but I also have one spike ALMOST everyday this past week, not everyday, and not all other weeks. Lately I’ve been having 140-150 spikes. Wondering if anyone else had been in a similar situation (without insulin, diet only) and has delivered a baby without low blood sugar/hypoglycemia... I’m going to cut back on my carbs intake significantly in these last few days but I’m worried the damage may have been done already...
