Diabetic and pregnant

Brandy
This is my fourth child but it my first pregnacy with type one diabetic my A1C is 6.8 and I feel that is really high when the dr said before I try to get pregnant I should have my A1C below 6 and close to 5.5 is there any other diabetic that can help me out and tell me what I should expect. With my third child I developed gestational but that was towards the end.
