Hi, I passed my routine 2 hour GTT at 28 weeks (my prebaby BMI is 32) with 4.7 and 7.2 results. I am now 34 weeks and was sent for a growth scan by my midwife. Baby is measuring big, so they are redoing the GTT next week, when I will be 35 weeks. Is it possible to fail a second later test? What can be done with only a few weeks left? This is my second pregnancy and there was no GD last time, no diabetes in my family and no symptoms in this pregnancy other than a baby >90th centile (amniotic fluid fine etc). I have an elective c section booked for 40 weeks, due to emergency one in first pregnancy. Will they bring that forward if I have GD? It seems a bit late going into 36 weeks to change my diet drastically.
