Hi. I'm no expert on Type 1, but having a low-carb diet will enable you to reduce your insulin dose (which must be done in conjunction with your nurse) if you are on a 'normal' diet currently. The result of this should be smaller blood sugar swings and I would hope better overall control. I'm assuming from your post that you are not currently trying to have a low-carb diet, but I may have guessed wrong. If you are a bit overweight then reducing carbs & insulin a bit should result in weight loss and sugar reduction and as I understand it having a good BMI improves the chance of getting pregnant although that's a generalisation. Note I'm not a medical person so my comments are only my suggestion for thought.
