Ughh!! Having Gestational Diabetes !!!!

First of whyy!?!? I wish I had a better doctor who was much more involved with me and my overall health! But anyway when I got diagnosed with GB, I had to wait to see a nurse in my hospital a week later. So I didn’t know what I was doing with my BS #’s so I would prick like the box prescription said and I would write down what I would eat too just to make sure I was doing it right and my Fasting #’s were in the low 70’s middle 80’s. But now after I got to my appointment there in the dam high 90’s to 100. But my nurse says my Fasting BS should be 100 and lower! Should I be worried about possibly taking medication because my BS is on the nose of the amount?! I’m nervous 😟 and don’t want to take medication or god for bid insulin!
