After taking nordette as an ecp 6 months ago, I had a normal menstrual cycle. But at times, a week after my period ends, I usually feel breast tenderness. I also monitored my discharge everyday. It was normal, but there were times that it has too much yellowish discharge for a day. Now, it has been 10 days after my period, I am now having a small amount of brown discharge. I'm wondering if it is a cause of std or hormonal imbalance or it is just normal or is it still an effect of the ecp i took 6 months ago?
