TTC with diabetes

Nanni • Enjoying being a mummy to a beautiful baby girl!
Does anyone have any experience if or how diabetes might influence conceiving?
I have been a diabetic since 1996 and for the last 13 years I have been on an insulin pump treatment which really helps me to achieve stable HbA1c levels. I don't have any long-term complications, but keep track of my health. Actually, I am less sick or affected by flues, colds etc. then most of my non-diabetic friends := ) But I wonder if it might aggravate conceiving?!
Thx for any shared experiences or first hand stories :)
