I'm 30 weeks and I was diagnosed with GD just before Xmas and have been monitoring my blood sugar levels 4 x day. So far my results have been fine the majority of the time with the odd high reading. I have my appointment with the diabetic clinic on the 4th Jan. At what point to they feel I can't control my blood sugar levels with my diet and move me onto medication? It would be good to prepare myself so I don't get too upset at the appointment.
