implant

Hey ladies !! No one ever responds to my posts which is unfortunate so maybe I'll have some people comment this time! Anyways I'm getting a new birth control method next week and I've chosen the implant in my arm .. I know I'm going to have major bruising because my skin is very sensitive .. I bruise from a nudge in the arm... Anyways any experiences ? Side effects? What should I be cautious about? I've read the pamphlet I received from my doctor but I want to know first hand experience is from people that have chose the same method!
