"i&#039;ve been on implanon since jan 2011 and for the first 6 months it was great. i didn&#039;t have a cycle or any side effects but then things went down hill. i have had back pains, headaches, my cycle is unpredictable i bleed from 5-14 days and have gained a tremendous amount of weight. i&#039;ve been bleeding so much to the point where my blood count has been low and my doctor has had to give me a pill form to take with implanon to slow the bleeding. the only positive thing is that i haven&#039;t got pregnant. i get this removed jan 2014 and can&#039;t wait. i&#039;ll probably go back to depo"
