Sept, I am in the exact same boat as you. 2 failed IVF's with really no diagnoised issues. I am feeling down and out myself. We are going to another clinic in January, not sure how we want to proceed from there, but we are going for a 2nd opinion. I still think I have implantation issues, but my dr seems to think otherwise. He tested me and my DH for a variety of tests, genetic, blood disorders, my DH had a SCSA, FSH, AMH. All within normal range. I asked my RE if I would benefit from adding some sort of predezone (sp?) for the possibility that it may be immune issues. I am grasping at straws here.
My current RE did tell me that he does not see a reason why I can not get pregnant and I am not a hopeless case. I also must take into acct my very good friend had her 3rd IVF and it was successful.
Hang in there, I know how hard it can be, especially around the holidays.
