"i had my implant inserted in july 2010, and the first 6 months i was very happy! barely bled, only gained a few lbs and no other side effects. the past year however has been absolute hell. i have 2 weeks of heavy bleeding followed by 1 week of none, continuously. i have also gained about 30lbs without changing my diet or lifestyle at all, as i am an active, healthy person. also about once every two months i get horrible stabbing pains in my lower pelvis all caused by side-effects. after finally confirming it was the implanon that is making me ill i have finally got an appointment to get it removed."
