As far as brown discharge is concerned, this typically means old blood that the body is just trying to get rid of, so unless there is a foul odor this is quite normal. As far as any other type of discharge, as it has lasted for more than 10 days, this really needs to be evaluated by a doctor to determine the cause. As you have switched on and off with birth control, it's possible that it is a hormonal imbalance going on. Other reasons for cycle abnormalities include stress, weight gain/loss, thryoid, infection, illness, medications, polyp, cyst, amongst other reasons. Please see your doctor for an exam and testing to determine what the exact cause may be.
