Hi Catherine,
It does mean that your chances of having GDD are higher - but certainly not a given.
The good news is that if you do have GDD you will be given the care that you need. You will be taught to monitor your bsl's (blood sugar levels) and given dietary advice to maintain a good level. You will be closely monitored.
I wish you all the best with your test - let us all know how you go. :hugs:
