Gestational Diabetes?

I was 30 weeks on Monday. I had my glucose test at 27 weeks. I passed by a point. My first pregnancy I passed generously.

This week, I've been very fatigued. Then today, I went pee constantly and my urine smelled sweet.

Has anyone else developed diabetes in the third trimester? I did call my OB and left a voicemail (I know amniotic fluid smells sweet, this is only when I pee, not any other leaking).
