Implantation or AF soon?

Li

Hi ladies,

Need some advice. Two days ago, I had a light pink discharge and yesterday I had some brown spotting and cramps. Usually I would just get a clear discharge when AF is coming soon. I am suppose to get my period today and checked that I had a little brown spotting. Any possibility of implantation or could it just be a sign of my PD starting soon?
