I'm on Ortho-Tricyclen birth control pills, and I'm on my last week of pills of my month of them. Usually when I get on those pills, into my 3rd one, I start my period- and by the time I'm finished with that week, my period is over. Well, this past week, I've been having this abnormal/irregular spotting. (its the week before I'm supposed to start my period.) I am now on my Thursday pill of my last week, and I haven't actually 'started' yet. About two weeks ago, I had gotten messed up on my pills (which has happened before) and had to skip a pill and resume my normal 'dosage'.

Has anyone ever had this happen before???
