"the birth control definitely works . however , in six months i gained 13 pounds while eating fairly clean and working out . so i went on a 3 week body cleanse and got a trainer - lost 10lbs. i went on a cruise and gained 10 pounds back within a week .  i still eat clean/workout and still the weight will not budge . i have horrible acne now . my skin was almost flawless before nexplanon . i just scheduled to have it removed next month . me and my partner use protection , so i feel like this birth control with all the weight gain and acne is not worth it . plus , my cycle used to be 4-6 days every month . now my cycle comes when it wants : spots , comes on , spots some more . i&#039;m usually bleeding 2 weeks a month and i&#039;m at month 7."
