gestational diabetes test

I will be 14 weeks tomorrow my ob sent me for a 50g glucose test last week because I had mentioned that I was thirsty all the time. I just got a call saying the test results were abnormal and would like me to do a 75g glucose test... I had gestational diabetes with my daughter 5 years ago diagnosed at 24 weeks and it was hell as I was insulin dependent feeling so emotional just hoping this next test will come back normal and everything will be ok 🙁
