"i got my implanon inserted when i was 18. it&#039;s been a little over a year with it and i&#039;d say the only side effect i have is mood swings and bad back pains, it&#039;s everyday. also i haven&#039;t really had periods and when i do it&#039;s usually spotting and last for four to five days most of the time it doesn&#039;t show. eating wise i&#039;d say i do get hungry a lot but i&#039;ve always been that way no weight gain. when i got it first inserted i actually lost weight. me and my boyfriend have been together since i&#039;ve put it on and sex drive is still the same if not better. i guess the birth control just depends on your body because my sister also got it but she got it shortly taken out because she would have periods for weeks. i&#039;d recommend it."
