I wonder. (I need to google that)
My mother has type 2 diabetes and through her experience, I found out that stress can raise blood sugars. stress.
Since you are working with a dietician, you are in good hands. I am sure she said stuff like low-glycemic index and switching all white flour stuff with bron (brown rice is so yummy! and quinoa is a full protein)
I used to be a vegetarian (a plump one) and only now as an omnivore, 10 yrs later (--I quit the veg because I felt I was getting sick and not doing right and just couldn't get there. and ttc, I felt I needed to "do" something different. That's me, not judging)
do I realize what I was doing wrong--for me. My body and psyche does much better on a low carb diet. Lots of vegetables and fruit and lots of animal protein. Almost no grains, once a day in the form of brown rice. Seeds and nuts too.
In fact the two times I managed to catch an egg was after being on a low-carb diet for a month and more.
Maybe try to write down every morsel that you eat, over a week and see if something is slipping in without your notice (I doubt that). Try to eat your fruit during the morning and at noon time leaving vegetables and nuts as snacks for late day into evening.
Cottage cheese is yummy as a snack (I know, I know but try it. The saltiness is welcome when having a snack attack) try roasting some almonds, salting them sparingly and toss those into the cottage cheese. trust me
Mornings: cottage cheese with apple sauce (you are going to think I am addicted to cottage cheese LOL. I eat it once a day for breaky, honest)
good luck, I know this sucks but count your days or weeks, this will soon be done and you'll be holding your sweet bean in your arms and will not be able to look away
me:42, DH 43
DS: born by c-sec Apr15'03, 9lbs5oz 41wks gest. (after 4 years of ttc, starting in 1998)
DD born by c-sec Oct 13 2007, 8lbs13oz 39wk gest. (after just under 3 years of ttc)
DS was conceived naturally the cycle following a cancelled DE IVF, using my good friend's eggs. She was on the verge of hyperstimming.
DD's nat conception I attribute to using OPKs like a crazy nut, eating grapefruit daily and using preseed. also 5 cycles of TCM ending 2 cycles before that lucky cycle.
