Farmgirl, I don't think it's anything you are doing wrong. I think it just comes down to the fact that IVF sucks, and while it will work for some, others find ourselves going through several stim cycles before they find one that works. If you have a gut feeling that something else may be wrong, it would be worthwhile talking to your FS about what further testing can be done, or what else can be done differently in order to get a different result next time.

Hang in there...
