"i got on the nexplanon on march 2015. when i was 140, i have recently got it taking out and i now weigh 170. i gained 30 pound while on this birth control. i also had mood swings, pain from the birth control to my elbow, head aches, my breast was always hurting. i didn&#039;t like this birth control method at all and i would not recommend it to anyone else as well. this and the depo shot has been the worst birth control methods i have ever used. i suggest not to use this birth control method at all."
