Okay so I've been on the implant since late July 2014 and since have had a light period once a month for four days at a time. This IS usually followed by a week or sometimes even two of brown discharge. However lately I am two weeks over due my period but have been having heavy dark discharge for over 3 weeks and it is incredibly embarrassing. It has no smell it just means I can't wear any pretty white knickers and sex is awkward because of it. I was just wondering if anyone else has had this problem and if they know how long it will take to pass or any remedies to reduce the problem. I'm panicked!
