Gestational Diabetes!?

Erika • Being four...there`s nothing I love more
I just got a phone call from my OB/GYN's after taking the one hour glucose test (25 weeks) saying I should take the test again (this time the 3 hour test) I'm so worried and scared! Could it still be that it's nothing or at least not diabetes!!...did any of you get it wrong the first time and fine the second time? How bad is having gestational diabetes!?
