"i have had the implanon for a year and a half now and so far it&#039;s been great. no period at all except for a couple weeks a few months ago of random spotting. recently though i have been experiencing horrible breast pain like you get when starting your period or when pregnant. (never been pregnant but friends say it&#039;s similar) and it&#039;s been going on for almost 3 weeks.the only issue is every few months for about a week i get bad breast pain. this time it&#039;s longer. anyone else have this issue?"
