Hi ladies , help please

next month I will have fet transfer , we have 7 embryos for PGS testing, waiting on the results. The retrieval day doctor gave a ERA brochure, he said take a look and decide if u want to do this . First we had no idea about it , after I read it OK it is a plus for the implantation but I don’t know if is worth it

The transfer is $3800 + medication

And ERA testing is $2500

Me and my hubby we are really confused because we want to do everything right but money is the problem also , on the other side is this ERA testing that important,?!!!

Any suggested who did it or did not
