"i give this a 5 because it does prevent pregnancy, yet so did my pill. switched because i wanted something i didn&#039;t have to remember to take. been on this for a year now the first 5 months were alright. but the last 7 months i&#039;ve noticed my period is heavy and gets me light headed. i have more migraines which i never experienced before implanon. sex drive is way down, bad mood swings, and constantly tired. before implanon i was extremely healthy, now i feel like crap almost every day. getting removed once insurance starts up."
