Gestational Diabetes

Is anyone else dealing with GD? I was tested and diagnosed super early, age plus family history. I am on insulin and also check bs 4 x a day. Once I got over the emotional stress of a strict diet and giving myself multiple shots a day I was ok but I can't seem to get my lunch time numbers down with diet excercise and insulin. It is very stressful and frustrating. I eat things like a turkey sand on low carb whole wheat bread and lowfat greek yogurt for lunch and have bs of 152 yet for dinner we had angel hair pasta w chicken and a caprese salad and it was 96!! Can anyone relate??
