Should The Oral GTT Be Done Again?

I had a non fasting blood test done, the result was that my sugar was too high 8.something, I ate about 3-4 hours before the test.
A couple of days later I did a fasting blood test, I had noting to eat for 12 hours and my results came back as showing my sugar levels being ok.
I am positive I have a sugar issue, I feel wrecked after I eat sweet stuff or carbohydrates as well as other signs of diabetes -exhausted all the time etc. I am 32, not overweight and there is a history of diabetes in my family, I had gestational diabetes when pregnant 3 years ago.
My question is should I go to the docs again and ask for an oral glucose tolerance test? Just because my fasting test showed as ok may an oral glucose tolerance test show that I have high sugar? I don't want to pester my doctor but want know for definite that it is not diabetes that is making me feel poorly.

Hello,
The criteria of diagnosing diabetes is ...
Any random blood sugar level above 200
Fasting blood sugar levels above 126
PP ( 2 hours after your breakfast ) blood sugar levels above 200.
You must get a fasting and PP level done to know the exact status.
Having a positive family history and having a history of gestational diabetes make you a highly suspective of having diabetes.
Thanks
