gestational diabetes question about diet and medication

Mom of 2 babies ❤️❤️
I've been on the diet for GD for three weeks. The numbers are getting better and I'm eating healthy for sure.  But yesterday and today the numbers were above the limits for breakfast and lunch; I had off numbers at least three times a week for the past weeks.  I don't have perfect numbers within range consistently.  
The midwives take copies of the chart say they are sending it to the doctor and that's it. Another woman who is on the same boat as me her doctor already prescribed insulin for her.  Believe me I don't want meds but I'm worried that I need them and they are just not paying enough attention? 
Edit: to add I'm having a csection so not sure if that's the reason they are not so concerned.
