Tessa - thank you for giving me hope! My biggest fear is that it's something intrinsic to me that can't be fixed. I really hope it's just random bad luck for me too!
Augie, I haven't had much time to research it, but apparently it contains some FSH, LH, HCG and maybe estrogen. I've just been crazy busy with work but plan to research it some more. I don't know how expensive it is. Luckily the fragmin should be covered by my work insurance because it's not strictly a fertility drug, it's used by people for a number of different ailments. In fact my dad was prescribed it recently for a blood clot in his leg.
Lisa, thanks for the info. I'm glad it worked for you! I did talk to my RE about PGD briefly a couple of months ago but she said let's keep working on things with fragmin for now and then we'll discuss other options. I'm happy with this, I don't think I'm ready for IVF yet. My abnormality wasn't one of the trisomies - they ruled those out. It was another random abnormality. I have also heard that MTHFR causes miscarriages and I'm surprised your RE said it didn't matter. I'm glad you got your rainbow babies!
