I did GTT after my second m/c as my OB wanted to check for insulin resistance. My test was came back with 'normal' results but I did alot of googling about insulin resistance in ttc and pregnancy and I found quite a few interesting articles. One which led me to starting a strict low GI diet..... Once our testing was complete and we started ttc again we got our forever baby.

I don't claim to have a huge medical knowledge on the topic but insulin is a hormone so I guess when it is higher or lower than usual it can affect your body incl reproductive functions in different ways.

Good luck with the testing and am sure your second bundle of joy will be on his/her way very soon.
