One hour was 8.1 and I failed the second. 2 week later I'm on insulin as even having 2 wheatbix and milk would send me over. Only risk factor was my age as before getting pg I had a BMI of 24.8 and none of the cultural ones apply to me.

At the end of the day it is not about the chocolate cake you ate last week - but if your pancreas can cope with 2- 3 times the usual load.
