Early Gestational Diabetes?

Le

I’m only 19w3d and at my appointment yesterday I was told I had some sugar in my urine but my blood sugar read 109; 100 being normal. I did have a potluck at work and consumed a lot of sweets. Now they are making me do a glucose test on Monday. What are my chances for GD? Or could this just be because I ate too many sweets before hand
