"i got my period a week after nexplanon was inserted into my arm march 2015. then i didn&#039;t have a period for a year and a half... i got a pap smear two months ago and ever since then i&#039;ve been getting my period. it&#039;s extremely heavy, painful, tender breasts. i&#039;ve experienced all of the side effects of this birth control and it&#039;s not fun. the only plus side is not having to remember to take a pill everyday. the worst part is the random heavy periods but it seems like everyone is experiencing this. my doctor told me it was normal!"
