IVF and embryo quality

I got pregnant from my first round of IVF with a fresh transfer. We did not do PGS testing since my doctor did not recommend It for us. At my 6.5 week scan they found a gestational sac but It was empty. I go back this coming Monday to confirm this is a miscarriage. I have 6 frozen embryos. I’m now wondering if i should PGS test the frozen embryos. It would cost roughly $6,000-$7,000 to do that. I’m torn on what to do. I can’t keep transferring and miscarrying, I would love some advice. I’m 29 with unexplained infertility. My doctor still didn’t recommend testing even after this possible miscarriage. Also we have 3 ICSI embryos and 3 natural fertilization embryos. Thanks!
