I had pink spotting hmmmm

Jennifer • Happy mother and wife ttc baby #3

So my period is 4 days away and had very light red spotting this morning and water cm I know cm isn't a good indicator but I normally don't spot 4 days before af I usually spot 1 day before could this be bleeding or af arriving?? The spotting did stop so that's why I'm also confused any suggestions would be great thanks :) been trying for awhile misscarried lastyear so trying for another one I also never had implantation bleeding before that's why its hard for me to tell anything can help this hasn't happened before accept the day before af not 4 days before
