This is from the NICE guidelines
Target ranges for blood glucose during pregnancy
1.3.1.1
Individualised targets for self-monitoring of blood glucose should be agreed with women with diabetes in pregnancy, taking into account the risk of hypoglycaemia.
1.3.1.2
If it is safely achievable, women with diabetes should aim to keep fasting blood glucose between 3.5 and 5.9 mmol/litre and 1-hour postprandial blood glucose below 7.8 mmol/litre during pregnancy.
1.3.1.3
HbA1c should not be used routinely for assessing glycaemic control in the second and third trimesters of pregnancy.
1.3.2.1
Women with diabetes should be advised to test fasting blood glucose levels and blood glucose levels 1 hour after every meal during pregnancy.
1.3.2.2
Women with insulin-treated diabetes should be advised to test blood glucose levels before going to bed at night during pregnancy.
I have an American book, whose author John Walsh I respect,This actually gives slightly lower maximum levels than the Nice ones so unless your specialist himself changes what he advises I'd try to keep to the lower levels as far as possible. (and you won't manage it every time...because your body and its needs are changing rapidly.)
It might be worth looking into the glycemic index , this index ranks carbs according to how quickly (and consequently how high) blood sugars are raised after eating. Weetabix has a high Gi of 75 There are some breakfast cereals (mostly oats and bran based) with much lower gis Theres a lot of information and a gi database on
http://www.glycemicindex.com/ After the theory, theres often some good recipes in the newsletter section.
And, try not to worry . I know it sounds trite and is d so difficult to do but stress also raises blood glucose levels so its a bit circular.
