"i have been taking implanon since january 2012, the first 2 years it was wonderful. no pregnancy, i actually lost weight, i had a monthly &quot;period&quot; which consisted of minimal cramping and being moody, yet no bleeding. on the 3rd year though, during mid february i started having a period. it is now the beginning of april and i have had 4 periods lasting a week each! i cannot deal with having a period after not having one for over 2 years! i love implanon but if i&#039;m going to continue having a period every week or two i might consider something else or replacing it earlier than the 3 year mark if possible."
