I had a ham sandwich and Diet Coke for lunch and the reading was around 10 and then evening I had a chicken burger and it was 12! Is it the carbs??
It will be the carbs, I have gestational diabetes and am on insulin every day and have a libre in my arm since 16 weeks, your body breaks down carbs into glucose so you need to limit your carbs and include more protein, fats and veg so that it's a paired meal x
What was the readings and what have you eaten? X
