"i started taking implanon   after i went off  depo shot . i had no period on depo. after a year on implanon . i got my period back not bad loved it for awhile . the 2nd one was different irregular bleeding. i have a period 2 or 3x a month. worst side affects are the periods not know when  they will come and when they will go away. breast pain and tenderness , painful periods at times. i&#039;m debating what to do next. i don&#039;t really want another implant. but, i don&#039;t want a baby either . my dr. said to try mirena but, i&#039;m acared to try it. i&#039;m undecided what to do next. maybe i should just go off of bc and use condoms . idk"
