I think getting the test done is the way to go too. You probably don't even have it. I ate loads or junk and whatever I felt like with DS1 and didn't have it. But with DS2 I had lost weight and was so much smaller than I was before DS1 and wasn't eating too badly, but I had GD.

Either way, diet or injections, it's the best for you and your bubba.
I'll have everything crossed for you if/when you have the GTT.
GL and all the best. Congrats on your little blue bundle! Boys rock!!
