Hello ladies, have anyone one of you had an ERA (Endometrial Receptivity Array) test or a biopsy and after earlier failed FET transfers got a BFP soon after? I consider doing an ERA test as it gives more insights into the implantation window and a biopsy improves lining but I also planned to have FET in September. I have 2 5-day PGS mormal frosties left and would not want to waste it if my lining is not receptive. I had some increased Killer cells in a blood immunology test, so the ERA could be an option.

What would you do?
