"i got implanon a little over a month ago. at first it regulated my moods. except once when i burst into tears over nothing, then was fine. other than that don&#039;t notice any weight gain, i have been getting headaches but i also have a cold so i&#039;m not sure if that&#039;s the birth control yet. i also sleep twelve to 14 hours a day. i love this birth control and i find myself poking it a lot. i recommend it."
