You had put it in 2011. So its life has ended in 2013. It is not good to keep it in the body after it is no more active. When we say it is not active, we mean that the hormones released from the implant are not in sufficient quantity to prevent the pregnancy; however, it is not completely devoid of the hormones. The very fact that you have started having irregular bleeding, the implant is releasing the hormone erratically in low doses. You should get the implant removed and replace it with another one if you still want to continue with the contraception. With such extinct implant, you cannot plan your pregnancy appropriately either. I hope you got the message.  </s>
