Reason for miscarriage

Caitlyn
I see miscarriages are very common. I'm devastated about mine and still can't understand how it went wrong. Apparently the baby wasn't lodging somewhere...I don't know. Can't even remember what the doctor was saying. Also something to do with my hormones because I am so irregular. Would anyone be willing to share what happened with your miscarriages? I want to try again. I'm just so scared it happens again.
