My period ended six days ago, and I am just now experiencing spotting. This is the first time I've ever experienced this and am wondering if it's irregular? I am on the nuva ring and had to put my new ring in six days ago after my week-long break (to allow for my period). My period was not completely done when I did this (which "cut-off" the bleeding) and I'm just wondering if that may be the cause of my spotting. Should I be concerned about this or should I just ignore it?
