Jess, how are your fasting readings going in the mornings? Are they up or about the same as when you were diagnosed? I found that the further along in the pregnancy I got, some of my readings started to creep up. Just this week a Lean Cuisine with rice in it, which hasn't put my BS up before, sent it above the 7. Think I am going to have to adjust my insulin dose and avoid that particular meal. Might have to cut out all rice all together, including the basmati.
Keep an eye on it and if any concerns call the Dr. Readings going up or down for no reason can be a worry as it means the placenta might not be working properly.
Let us know how you go.
