hi amelia
be careful u don't drive yourself potty reading about all the scary things that can happen to pregnant diabetics, I did this when I first found out I was pregnant and whilst it's good to be aware I ended up convincing myself I was going to give birth to some sort of mutant, if I even got as far as giving birth at all.
I think diabetes care for pregnant ladies is very good now, it gets a lot harder as you get into the third trimester though, my insulin resistance has gone crazy so I'm now on apx 5 times as much short acting as before and double long acting.
I've been having a lot of hypos but they don't harm the baby, the highs do, so I kind of can live with that I think better too low than too high which although obviously is not ideal I've come to the conclusion that it's impossible to get it spot on, so i err on the side of injecting a bit too much rather than not enough.
Some advice - go and see your GP straight away get them to make an immediate referral to antenatal you should be seen by a specialist within days not weeks of finding out you are expecting.
Do all you can to get your blood sugars down NOW
Test 8 times per day, every day - before and after every meal and before bed. They will tell you to aim for below 6 before meals and below 8 one hour after.
(this worked for me) - inject for your snacks not just your meals unless you are having lowish carb snacks.
learn to correct your post prandial highs (above 10) with a correction dose of bolus
don't overtreat any hypos, if you do you'll need to inject for the excess
Basically you need to learn to become a very good feedback mechanism which requires that you test, and correct, on a pretty much continual basis.
I got my hba1c down from 9.6 when I first realised I was pregnant to 5.6 three months later
baby seems to be fine so far
hope that helps
