Chance of another missed miscarriage...

Kate • Wife and mommy to a 2 Yr. Old boy and 1 angel baby boy. Pregnant with our rainbow baby 🌈
I had a missed miscarriage in April @16weeks. Had chromosomal testing done on the baby and everything came back fine. Does anyone know what the chances of having another missed miscarriage is? Or what there Dr. said about a missed miscarriage and future pregnancies? My Dr. Said it was just bad luck and couldn't pinpoint what happen.
