Spotting or my upcoming period

On Monday my period was due in 9 days. I had spotting and though that that my period is mabey starting earlier this month. It was only there when i wiped one or 2 times and then it was finished. This whole week i had light cramps nothing to major. My prriod is due in 5 days. Could it be implantation bleeding? Or was the spotting a sign of my period coming up.
