"i have had my implanon in since february 2011, so 14 months. it has been really great. at first i was gaining weight, but that was because of unhealthy habits. now that i am up and moving more, drinking less soda and more water, i am losing faster than ever. i get a &quot;period&quot; every 3-4 months or so, and even then it is just 3 days of slight spotting. the only negatives i can think of are slightly decreased sex drive (which you can work through) and sometimes feeling a bit depressed (which usually lasts less than a day). if you are thinking about getting implanon and are turned off by the possible side effects, just try it. it can be taken out any time. and remember, there is no &quot;natural&quot; birth control, everything has side effects."
