"i got the implanon in 2014 and for a long time i loved it. it&#039;s a highly effective method of birth control, and for almost a year i had no period. but then my period started back up again, happening at weird times and happening for weeks at a time. sometimes i&#039;d get off my period and then and up bleeding the next week. it was terrible. but what was worse was the weight gain. i probably gained 20 pounds. i actually do exercise frequently. i walk almost every night for about 3 miles and then a few times a week i&#039;ll go to the gym. but i wasn&#039;t losing any weight! and it gave me acne like all the time. 10/10 would not recommend."
