yes, I was under the diabetic consultant from about 14 weeks - levels were high at 12 week blood tests.
To be honest with you, 4 units of insulin is hardly anything - I think I lasted two weeks on that - went up in twos - I have a recollection that I ended up with 20 units after some meals, and 18 after others - it became a bit of a game with me (bit sad, but...) to see how long I could manage levels before I had to up the units. It does get you down after a while, but I had a chat with a friend whose husband has had Type 1 diabetes since a young age, and has been injecting for over 25 years! Kind of put it onto perspective for me - I had at the most 25 weeks of injections - so there was an end to it.
I did some internet research while pg and found american sites were the most informative, as it is more comon over there - I was led to believe that the insulin has no effect on the baby, and that uncontrolled sugar levels can lead to big babies, who can have problems with breathing, etc, but those are only statistics. I can only speak for myself, who has had two babies, with Gestational diabetes with both - DD was 10 14 born, and is now 6 and as skinny as a rake, and Ds who was 8 8 at 38 weeks (so would have been ove 10 full term).
Incidently you dont have to have a c-section to give birth - even though I had c-section with DD, I was offered the option of induction, and therefore vaginal birth, with a 50 /50 chance of having a section. I was neither encouraged or discouraged by the Consultant, but I opted for a section as DD was a large baby, so DS was likely to be big. Has birth been discussed with you at all yet? Do you find your consultant helpful?
I will try and find my blood sugars book - I think it is in the box with my monitor - I kept it as a reminder, and if I can give you any indication of what levels I was on and levels of insulin, then I can, if you would find it helpful.
Finally dont worry - it is easy to forget that you are actually growing a baby in there - what with all this injecting, etc, but dont lose sight of that.
