Congratulations on your upcoming wedding and as a diabetic it is a really good idea to start preparing for your pregnancy in advance, since we are regarded as 'higher risk' than non-diabetics. This is what I was advised and what I did 9 years ago when I had my son:
- start taking 5mg folic acid, you can get this on the NHS. Also, start taking a really good quality prenatal multivitamin. Ask your doctor to check your Vitamin D levels and take a supplement if it is low.
- The doctors advised that my HbA1c should be below 7, and of course the lower the better. I would suggest you start closely monitoring your BS levels and keep a diary if you can, and continue this whilst pregnant. Pregnancy can really mess your levels around and so the closer eye you have on it the easier it will be for you and your doctor to manage it. Usually insulin requirements rise during the pregnancy, I was ok the first semester but by the end was taking almost double my usual doses. And, as soon as I had my son, my insulin requirements dropped back down again to pre-pregancy doses.
- Try to eat a really healthy diet, low carb, lots of fresh vegetables, healthy fats and good quality protein. Oily fish 3 times per week (salmon, mackerel, sardines, anchovies) as these are low in mercury. Don't eat tuna. Try to avoid processed junk food. And, take all the usual precautions pregnant ladies are advised such as well cooked food etc.
- When my son was born he was in the intensive care unit for 3 days while his BS sorted themselves out. He isn't diabetic, but as my BS were not as low as a normal person (even though they were well controlled) they were still higher than normal, which meant his pancreas was producing more insulin to deal with any higher sugars. So, once he was born his pancreas had to adjust to produce a normal amount of insulin.
Best of luck, I hope all goes well for you during this exciting time. X
