I'm 25 weeks, couldn't complete the GTT as I was sick but fasting reading was high. I have a glucometer for at home although don't have many strips for it and due to working hours can't test super regularly yet, so far it's my fasting readings that are an issue. They have been fasting 5.7, 2 hours after lunch 6.5, 1 hour after tea 6.1, then the following day fasting 5.6 and 1 hour after tea 6.5. Midwives think I do have GD but it's borderline, I'm going in tomorrow morning for them to do a spot check and HBAC1 bloods (which previously have all been fine), baby is not measuring big she is measuring a bit small. Can you be borderline or is it a set yes or no? Not sure why my fasting is high? Of course I will still be making dietary changes.
