Lastchance75 I've had a OE PGD normal fail and from my readings it is not uncommon. I was on full immune support with Wazza when it failed. I'm now in TWW with 2 more OE normals and am not feeling positive. My understanding is that PGD normal is just part of the picture and they often don't work, they just have a better chance than an abnormal. They can still result in miscarriages, ectopic pregnancies, and blighted ovums. Do you have endo or Adenomyosis?
