Is my fat keeping me from getting pregnant?

[kelseykrogers]

So I'm not yet a mom, but my husband and I have been trying for many cycles unsuccessfully. I visited a doctor a month and a half ago about it, and one test showed that I have high insulin levels, though the test when I was fasting came back normal. In my follow-up visit, we talked a lot about weight loss, though I don't know that it was related to lowering my insulin levels. In that regard, she just wanted me to take Metformin. I have read Intuitive Eating and just looked into Health at Every Weight - looks good - and I really think that the perspective they offer is very accurate. But I don't want to keep myself from having kids. I feel like it's all my fault that I'm not pregnant yet, that if I weighed less or kept to a diet instead of trying to practice IE, then I would be pregnant. It's an awful feeling. Any advice?
