Hi Mellybelly..... I was thirsty, which is a symptom. Tired and cranky, but they are also pg symptoms. Ummm possibly for me the massive decrease in weight gain was a symptom. I cant quite remember how she explained it but when the sugar etc isnt dispersed of properly the body turns to the fat stores for energy. The weight loss is simply due to diet change since the diagnosis. If you do have GD the doctor will assess how it will be treated, they try diet control first and if that doesnt work then you need insulin, like me
