I was tested about 12 weeks, and I did not pass either glucose test, so I have gestational diabetes. I didn't have any symptoms though, just a family history of diabetes.
They told me I had it at 6weeks but I made them recheck me agian and it was negative in I'm 19weeks now. Crazy huh but I didn't have the symthoms u have
I know that I just didn't know if there was a way of knowing if you had it earlier
They don't check you until 24-28 weeks.
