Fertilysis tests - anyone done them?

How did you find them? How long did results take for you? What made you do them?

I’m thinking of doing the full package : NK cells (blood test), uterine microbiome (menstrual blood swab) and vaginal microbiome (vaginal swab) ahead of doing a transfer of euploid embryos as I have unexplained infertility, and if I can, I’d like to find a reason for the infertility before transfer so we can max the chances of success. Anyone done this or have any thoughts on doing this?

I’m in the UK if it matters.
