I have had this arm implant since June 4th 2016 and it is now January 14th and it is NOT GOING AWAY. it is a light period but the blood is bright bright red. I only need to use panty liners. My doctor said it can be irregular and bleeding can last a long time, but 6 months?! Really starting to get annoyed. I have no cramps, but I do break out more. The blood also smells a little strange, not like my normal period. It smells bad honestly.. sometimes my period will stop for like a day but then start up again.
