Yes, preexisting I guess, but it never showed up before - probably was well managed by my diet and exercise). I was on insulin (
humulin 70/30) by 10 weeks - started on six units in morning and 4 in the evening and went up to 10 in the evening and 4 in the morning in the first few weeks of adjusting.
Anyway, I was able to keep levels stable and within target (<95 fasting, <120 2 hrs post eating) up until about 2 weeks ago. Am now 31 weeks.
