Has anyone had karotyping done after recurrent miscarriages? Did the results provide any answers as to why you had more than one miscarriage?

I've had one ectopic, two MCs and a handful of chemical pregnancies since having a healthy baby in 2015. Day 3 testing was normal, blood clotting tests were negative and my thyroid is normal. I don't have an ovulation problem and my luteal phase is always 13/14 days. My RE told me it's either a chromosomal issue or just bad luck.

I really want to believe that it's just bad luck because I'm afraid of what our options will be if my husband or I have bad eggs/sperm.

Any experiences?
