Inside belly button tender/sore for days now a bit of blood expelling. Also noticed a bit of vaginal bleeding? Period NOT due. Connected?

Possibly. A period can come at a time other than when due if there is stress of any sort on the hormonal signals. If you have bleeding from your belly button during your period, you could possibly have an endometrial implant there (Endometriosis). I would see the doctor to get your umbilicus checked for infection and possibly for a pelvic exam if you have not been evaluated recently or are sexually active.
