Glucose Test Today. QUESTION

Kaye • OB/L&D TECH. Second girl due in November. Hoping for a vbac

Hey ladies I have my ph so wonderful glucose test today. The first one (and hopefully only). My question is ... I have problems with my sugar dropping bad. They told me I did t have to fast for this or anything. So if I eat my breakfast and have my coffee now (it's 6am) and the test is at 1030 .. I should be all set right?? It won't spike me super high by eating now ?
