"i have been on implanon now for almost 3 years, and i am going to have mine replaced shortly. i have had some mood swings but i can contribute most of them to everyday life stressors. i am a mother, employee, student, and companion so stress is knocking at my door as i type. but i love that i have only had minor spotting, very little weight gain, and a barely noticeable scar. i would recommend it to every one i know!"
