Yesterday I got the arm implant, Nexplanon. I've been on the pill for roughly three years but I'm moving because of grad school and I'm not sure where I'll be after that and not having to think about my birth control for the next 3-4 years sounded ideal. I thought I did enough research but now I'm a little worried. Did anyone else with the implant experience serious bruising or pains that feel like it's moving? Am I panicking over nothing or should I call my doctor?
