False positive for GD?

I was diagnosed with GD last Thursday and have been testing my blood sugar 4 times per day since Friday and my numbers have pretty much all been within normal limits aside from one reading of 133 2 hours after I ate a morning star "chik patty" for lunch. Yesterday I went to a clambake and had SO many clam cakes with chowder followed by a steak dinner with potatoes and corn on the cob and my reading was 119 2 hours after. Today I had a cheeseburger with pasta salad and a broccoli and carrot medley and my reading was 109. I'm just so confused if I truly have GD or not....
