I just wanted to share my experience, in case any others out there might be running into the same problem I had.
I tried conceiving for 2 years, but not until losing a few pounds was I able to get pregnant. I had all the risk factors for insulin resistance (belly fat, family history, some PCO symptoms). I never knew that losing just 10 pounds could help.
The more I read and learned about insulin resistance, the more surprised I was to find how pervasive and damaging this condition is. If you have any of the risk factors, perhaps diet, nutrition, and (perhaps) medication might work for you, too.
Anyway, I have more details on a blog, if you'd like to check it out...

Good luck,
