Sorry, A bit late, hope you are doing well! ketones in pregnancy are not good, especially in teh 1st 3 months. I am not awware of a safe level (not saying that there isn't one, just that I don't know what iit is!) if your BG is creeping up to 11, I would get an appointment with teh diabetic midwife, and get some advice.
I have had 2 (naughty!!!) children, and have been T1 since the age of 4. I seemed to be at the hodpital all teh time, going to check up, and gettig frankly daft advice from teh consultant, BUT the midwife was fantastic. She understood how difficult it cand be, but at the same time, helped me improve my control. I have never ha such a brilliant HbA1C. If you are getting ketones, go and seek help.
This isn't supposed to be a doom ad gloom post. I am not saying that baby is being harmed, but everything you can possibly do to help the little one has got to be done. As I said earlier, now you are 6 months, teh real danger time has passsed, so all should be well, but uit really is worth getting everything checked out, and get all the help you can take care of both of you.
All the best of luck, J
Oh, and for me, 1st pregnancy, awful, got pre eclamsia and blew up like a balloon, 2nd time around, great, only complaint was being called a "typical diabetic" with that roll of the eyes, despite have HbA1C in the 5s. Baby was big, but healthy!
