Between period discharge?

a week before my period i have a brownish discharge. I was on the pill for 4 years and came off it 5 months ago due to this reason. About 14 days into my pack i started with this discharge. I came off the pill hoping it will stop and my cycle would turn back to normal(no discharge). What could it be? I have no pain or anything sinister. Is it just part of my cycle and hormones?
