Gestational Diabetes

Gemma
so today I went to do my GD test (the two hour one) and I was told to fast for 9 hours. During my pregnancy I've had pretty awful morning sickness but it's gone now unless I don't eat, but I felt fine the last time I needed to fast for a blood test so I assumed it would be okay. I got there and they took my blood and I drank the glucose and literally 2 MINUTES before my second blood test, I threw it up and now I probably have to redo it. But I expect I'll throw up every time I do it. Anyone have any tips on how I can avoid throwing up whilst fasting? (Ps. I'm allowed to drink some water.. But not much)
