Glucose test tomorrow morning

C
I have my glucose test in the morning, I'm so nervous, do they draw a lot of blood? I hate getting in the car without having anything to eat I get so carsick and my doctors is a little far 😰 and I just started feeling pain in my pelvic/vagina area bone 😖 has anyone else? I will be mentioning it to my dr but he always seems to blow me off
