Helppp!

Breanna
Been spotting for six days now... Very light, today medium. First five days were very pink, today very dark red, almost red-brown. Period not due until December 6th. Not exactly sure when I ovulated. Been having slight abdominal pain, no cramping though, just twinges. Boobs not sore (usually get sore 7-8 days before EVERY period). Opinions!?
