Sweet tasting vaginal discharge

Lisabet
So, I tasted my dishcharge last night because I was curious. It was sweet, it's never tasted sweet before.
I looked it up and it could be diabetes. I'm REALLY worried now. I'm not overweight, my BMI is fine.
But I'm kinda freaking out now. 
What should I do? What have you heard about sweet tasting vaginal discharge?? 
Please, I need help!!!
