Failed 1 hour glucose test

Kelsie • Wife, Momma to 3 girls, expecting baby #4! 🤰
So I failed my 1 hour glucose test with a 149 (need 140 to pass). I'm kind of freaking out about he 3 hour test. I kind have sworn I was going to pass it! No one in my family has diabetes and/or gestational diabetes while pregnant. 
Doctor took blood 5 minutes too early, also. Maybe that could have caused the difference? (Looking for sight of hope!) anybody have similar experiences?
