ERA in adenomyosis

Dear Doctor, I would like to ask for your opinion of ERA specifically in women with adenomyosis. I had an ERA which showed that I would need one extra day of progesterone (so transfer after 6 days). However, a new doctor came at my clinic and he does all transfers after 5 days of progesterone. After that, I had three transfers: one at 5.5 days which worked but resulted in a late loss, and two at 5 days with no implantation (not even a chemical). What do you think in the context of adenomyosis? Thank you very much in advance.
