Reoccurring loss questions

Whitney

Today I found out my third fet with a high grade pgt tested embryo has failed. The first one was a chemical, the second was a mc at 7 weeks and this one didn’t even implant. We were originally diagnosed with only male factor, but now I am questioning our diagnosis. I am wondering what questions I should ask and what tests I can talk with my doctor about possibly getting at this point. Thank you.
