hiya - sorry to hear your struggling with the insulin. I'm pregestational diabetic, but have had to go on novorapid since getting pregnant and keep my bg's real low - I am going hypo on a daily basis, and trying to sort it out with the nurses but have accepted that some hypos inevitable, would rather that than be too high and affect the baby's health, so yes you may have to accept the insulin for the baby, as I have, but if the choice is a few hypos or the risk of things going wrong with the pregnancy, well I know what I have chosen....
It is hard though. I get p'd off with it all on a daily basis. Good luck
