Endometrin receptive assay (ERA)

My ERA test came back with pre receptive which translates to their prediction that I need to transfer one day later than I have been doing. I luckily also had a biopsy done two days later and have paid to have this tested. I'm hoping that says post receptive so we know I need to transfer after six days of progesterone instead of 5. Has anyone else had an era done? What were your results?
