Failed 1 hour glucose test a while back..

Alexis • Expecting our sweet baby boy in April.💙 I thank God for giving me such a wonderful opportunity!
So before I was pregnant.. A week or 2 before I became pregnant I had to take a 1 hour glucose test as part of a panel for PCOS screening (I was worried) and I failed the 1 hour glucose test with a 162 (normal was 119 I believe) I'm 19 and I was wondering if any of you (NON PREGNANT LADIES) failed a 1 hour glucose test. But passed a 2 or 3 hour one?? 
By the way, when I got my blood test results back, my insulin levels were normal, but it was my blood sugar they were worried about.
