Possible Implantation Bleeding

I am 9 DPO and currently supposed to start AF on Monday. Two days ago when I went to the restroom first thing in the morning I had some spotting (I don't usually spot) just enough to wipe and it would be gone. It stuck around for a couple hours then stopped. Then yesterday there was nothing and then today the same thing happened. Spotting in AM and nothing since. Could this be implantation bleeding? Or am I just getting my hopes up for nothing?!
