PGS testing of embryos??

Amy

I am starting IVF and they are suggesting testing of the embryos to help determine viability. I am on the fence. I know being 42 it is safer, but if I had gotten pregnant naturally or with IUI, I wouldn’t have that information. Trying to decide if I go all in and pay the extra $$ or do I just put in the best embryos I have and leave it up to a higher power?? I am not interested in knowing sex of the embryos and would request to not find out prior to implantation. Does anyone have any information that swayed them one way or another?? How about losing embryos to the freezing and thawing process?? Any input is appreciated....
