"i&#039;ve had my implanon since october of 2011. i spotted for a few days right after i had it inserted but then i didn&#039;t get my period for well over a year! i&#039;ve only had my period once since then and i&#039;m happy with that. on the other hand i have noticed various mood changes and a little depression. the worst part is my sex drive has gone down so much. my husband doesn&#039;t believe me when i say it&#039;s the hormones (i almost didn&#039;t believe myself at one point) but after reading all these reviews i&#039;m sure it is. it&#039;s a great method of birth control but definitely affects everyone differently, so far as not getting pregnant, it works."
