"i got this as my first birth control experience at the age of 17. when i first got it, i didn&#039;t realize that all of the side effects i was having were caused by this. i gained some weight. i was moody and had zero sex drive. i also had irregular periods which i never had before. i would bleed for a couple days after every sexual encounter. i won&#039;t lie, i had a promiscuous year during year 3 of having this. i didn&#039;t have a single pregnancy scare. but after the first year of having implanon, my side effects subsided. i love it. i am so glad that i have it. i had it replaced last summer and saw a few side effects from it. just irregular periods again. but it is so worth it. a year of side effects is nothing compared to being a mom."
