MY BELLY BUTTON IS BLEEDING!!

Praying2bMommie
My period came 5 days late this month & my period only last 5 days every month. I have noticed yesterday & today my belly button is bleeding. Not a lot but there were spots in my panties from it. I read inline that it could be from left over fetal life. Could have I been pregnant & lost it or do miscarriages happen before your period?
