Gestational Diabetes Fasting Numbers [on]

Moms with GDM, who had high fasting numbers (greater than 5.3), what hacks did you use to drop your fasting numbers? FTM, 28 weeks and my day time/ post meal numbers are fine but my fasting numbers in the morning are between 5.4-5.8, and I would like to avoid being put on insulin, if possible.

Any tips and tricks are much appreciated!
