I have been on the pill for 2 years now and have had no random bleeding, discharge, spotting or anything like that. It's been working completely fine for me. However, yesterday I had a brown discharge which looked how it would if I was on the end of my period. I'm really confused and don't understand what this could be and thought I would ask to get some more information. I have booked a Doctors appointment for next week to get more information. Should I be worrying?
