Pure coincidence or possible reincarnation?

Do you think what happened to my friend is pure coincidence or the work of some devine intervention? First she miscarried a baby girl 4 months into her pregnancy. That was the very first time she was pregnant. Then the following year, sadness stuck again. She gave birth to a stillborn baby boy.

Some time went by. Her 3rd pregnancy was successful. She ended up having fraternal boy and girl twins. Plus they were born in the same original order. The girl came out first and then the boy. Possible reincarnation? Or just pure random coincidence? No one in her family ever had twins.

A couple strange things that she can't explain has always been happening to her. Now this happened. She feels as if the baby boy and girl she lost previously came back to her.
