Hi, just a note of support - I was diagnosed in March 2001 whilst in the very severe last throes of dka, the previous year I had been told I couldn't have children (not diabetes related). Embarked on ivf treatment February 2002, and produced healthy twin girls at the first time of trying!
What I'm really saying is that there is help out there, and being diabetic does not stop ivf being offered, nor does it make any difference to the success rate of live births. Whilst pregnant I tested and ate regularly, something that hasn't always been possible while looking after the children! I too get mysterious highs/lows, and days when no matter what I eat I can't get my blood up. Only another diabetic can understand what you are going through but you are most definitely not alone.
Hugs and chin up chicken!
