"i had implanon inserted in summer 2009. i bled almost constantly for the first 3 months, and i almost gave up. i also noticed that i would get headaches if i didn&#039;t eat a good breakfast. the headaches stopped when the long bleeding stopped. my acne is a little harder to control now that i&#039;m on implanon, but its not bad. now i have light, 3-4 day periods, usually more than a month apart. no weight gain, i&#039;ve been skinny my whole life though. no need to use a condom! my long term boyfriend and i really like implanon, it really is a &#039;no worries&#039; method for us."
