"i have had the implanon for three months now, the first month nothing happened, the second month i had severe mood swings &#039;pretend periods&#039; (acts like i&#039;m about to get it but nothing) and no sex drive whatsoever. the third month the mood swings left, &#039;pretend periods&#039; gone. sex drive off and on. now i just got my period, had it for two weeks now. mild cramping, its all spotting. i had horrifying painful periods before that were irregular, horrible. so far this birth control has been worth it. i recommend it. i don&#039;t have a scar..only mild bruising and i can&#039;t lay on my arm or put pressure on it or it&#039;ll feel weird or hurt."
