"i started this birth control in february 2012. the numbing stuff hurt just like a normal shot, but after that i could just feel her touching my arm nothing else. for about a week later my arm was bruised and slightly sore when i lifted things, but nothing bad. my arm is fine now, just a tiny scar and of course you can feel the tiny implant in your arm when touched. i think its awesome! i had spotting for a few days the very next month, but i haven&#039;t had any bleeding or spotting since them. i have gained maybe five pounds since starting this, but also haven&#039;t been keeping up on working out or eating healthy so who knows which it&#039;s from. no mood swings or loss in sex drive. everything is great and its awesome to not have any pregnancy worries."
