Gestational Diabetes

I just got my OGTT test result and turns out my third result which was the 120min was a little high 9.7 the doctor told me to come tomorrow and my mind is not at ease, as I am wondering if you're pregnant and have gestational diabetes do the doctor will prick your finger for glucose blood test? like often? because I've done that kind of finger prick test before and I hate it I rather get blood drawn from needle then finger prick.
