Sorry, I can't answer your questions, BUT I can say WELCOME to the Diabetesforums, you will find lots of great information and support from a many women going through the same experience you are contemplating.
Congratulations on bringing those numbers down.
The most important thing to consider as you contemplate children and the future is to keep your attitude positive! So if it takes a little longer it is imperative that you enjoy the process. Just keep thinking "it is hard work, but somebodies gotta do it!" )
Keep up the good work and I am sure you will do well.
