Battling with gestational diabetes

Since I found out about having gestational diabetes on Friday, I have been careful about what I eat during my meal time. This is tough. I've done this diet while I was pregnant with my first child but it is still hard for me to follow. I am only allowed to have about 30g of carb (it is about 2 slices of bread) every time I eat. I can have a lot of meat since it does not contain any carb but I still need to make sure count the calories. I also have to eat stuff that high in iron as well due to anemia. This pregnancy is really tough on me. At least I am some what recovering from my anemia but still not at the normal level. Wish me luck that I can stick with this routine of watching my diet for the next 3 month. Thanks!
