"i first got this bc when i was 16 got it removed at 19 i am now 22. this was my first bc ever and i have to say it was excellent as far as prevention. i had little to no periods throughout having it for the full 3 years. a lot others experienced at least 15lbs weight gain, however that wasn&#039;t the case with me. i was 120lbs when i had it put it and than i blew up to 165lbs in first year and a half (no change in diet) i have no idea how that happened and than all of sudden i started to shed off the pounds in the last year of having it and went to 115lbs i don&#039;t know what changed (still no change in diet) if anything i was eating more sugar but losing weight (weird) i know.i plan on having another put in, in 6 weeks after delivering hoping4best"
