"i absolutely hate this birth control method! i had the implant placed in may 2015 right before i left to college. first 3 months i was fine. then it got awful. my periods prior lasted 3-4 days and were super light. now they last 20-24 days and are relatively heavy. i never had acne in my life and now i get major breakouts and my back now has bacne!! not to mention that when i got this inserted i was 128. i&#039;m 5&#039;3 btw. and i was a 3 sport athlete. very in shape and muscular. i never had a problem losing weight, ever! i could always bounce back and be fit. from when i started college in august 2015 to the end of freshman year may 2016 i gain 8 pounds. so i was 136. now i&#039;m 166. in 2 years 40lb gain! i cannot lose weight to save my life! :("
