PGS testing

Hi all. This is my first time doing IVF. My retrieval was this past Tuesday (11/30). They retrieved 31 and 17 fertilized overnight. 5 more fertilized late and look average. Sunday will be day 5 and the embryologist just called me to let me know that it’s looking like there will be a large amount that would be viable for PGS testing but the package only covers 8. We can send as many as we’d like for 250$ per embryo more. We have had 6 miscarriages with no known cause. Embryo quality is basically our last possible cause. Would you pay to send more? Or would you just send the 8 and freeze the rest that look great?
