After 9 consecutive failed transfers (including 7 PGS normal embryos), we've finally decided to do an ERA. Our RE wasn't a fan of the ERA as there's mixed evidence that it makes a difference, but we've exhausted all other testing options.

It seems that 75-80% of people who do an ERA are in the right window, and nothing changes. I'm wondering if anyone has done one and ended up outside the receptivity window and changed their protocol because of it?
