I have been taking birth control for about a year now and have never really spotted in between periods unless I skipped my period that month (by continuing the white pills). But now I am spotting and the bleeding resembles my period but I am not supposed to be on my period for about another week. I had my period last month so the spotting isnt a result of skipping it. Also, I have been stressed recently because school just started. could that be a reason for the spotting? should I be concerned?
