I have had the Implanon rod BC for almost 3 yrs now. My scheduled date for removal is Jan 2 2013.. I have read that they can go "empty" before the 3 yrs are up. Which makes me wonder this. I have NEVER had a brown period before. Tmi- I know I'm sorry. But on the 6th I wiped and it was a thick mucus only brown, I freaked a little! I know it may be old blood but anyways, every 4 hours I would change my tamp and it was 1 drop of brown and the slightest hint of deep red each time. It lasted 3 days now its gone! It didnn't smell, I don't have cramps but I am nauseated. I ate just twice in 3 days but now I can eat but only so much! I pee constantly and keep taking cat naps. I will get a test but does tgis sound like a pregnancy or just a glitch in the ole AF
