Gestational diabetes help?

Lex • Mommy of a beautiful princess👶🏼👑
So I went two days ago for my glucose test and my results were high. They called and asked me to re-test for not 1 hour but 3. I really don't want to end up having gestational diabetes and I don't want my baby to be harmed or obese in the future of when she's born (I'll love her no matter what of course). Has anyone had this happen and the results came back ok? Help!
