I am 15 and was in a sexual relationship for the most of the previous year and was on the contraceptive pill. I came of it three months ago and have only had one normal period since. Two weeks ago (when my period was due) I had brown secretions (that I usually have before my period) for three days and two weeks after another few days of brown secretions. I am very confused. I haven't had unprotected sex since but I don't know what is the cause. Please help me.
