Mine eventually became a success story, but did not start out that way. First I was diagnosed with Unexplained Infertility, a condition which is as frustrating in many ways as not knowing what is wrong because it's so vague. I found a center that did further tests and narrowed my issue.
Eventually I did go on DHEA for five months and at last had a successful pregnancy with IVF and pgd. (I put all that in on sentence just to show how much I've learned in the last two years!)
Best of luck to all!!!
