I Had My Bloods Tested Due To The Fact I

I had my bloods tested due to the fact I am on cholesterol meds and they are tested every 3 months. My question is my glucose came back at 108. Should I be worried because I had gestational diabetes when I was pregnant in 1991 and was on insulin for 2 months and then had my daughter at 35 weeks? Afterwards my bloods were tested and I never had a problem.
