Here's a little background first..I've been ttc for over 4 years now. I've been to 3 reproductive endocrinologists, went through their array of tests, medications, 2 rounds of artificial insemination and diagnosed with "unexplained infertility" I was told there's no reason we can't get pregnant on our own....but it still hasn't happened. I "quit" all specialists about 2 years ago. Now, in ttc, all of us have heard the "just relax" and other forms of "advice". Recently, a girl I recently met suggested metformin. It had worked for her. My family dr put me on it this month. I don't have diabetes or pcos. Has anyone taken metformin and had success with it?
