My ob plans to put me on something called nexplanon it's inserted in your arm & lasts 3 years . But recently my sister told me about her friend who choose this BC option & it moved from where it was supposed to be now I'm confused on which BC option I wanna do. I know every woman is different but I would like to know what BC your on & what are the pros & cons of it . I'm scared to get the mirena as well with fear that it will move as well. I'm also breastfeeding
