Help! Implementation bleeding?

An
So I ovulated (I believe) 10\27...I'm due for my period 11/10. The past 3 or 4 days I've had like sharp cramps and I don't normally have cramps that feel that way or this much before my period. Today I don't have as much cramping but when I went to the bathroom my underwear had CM that was like a light tan color. I don't normally spot this early or that light...could this be implementation bleeding? I hope so! Please let me know if you has these signs!
