Could I be pregnant?

Felisha

Alright everyone... period is late by 2 or 3 days. Started having brown stringy discharge 2 days ago. It's only when I wipe. Yesterday it was a little heavier, but still brown and only when I wipe. Today i was a little redder but still only when i wipe. So could this be my period or implantation bleeding? Give me your thoughts please!
