"i got nexplanon about 3 months ago and i love it. the only thing that was uncomfortable was the numbing shot. you don&#039;t feel anything after that. my arm hurt for a few days but that was expected. my first period was a whole week but very light and since then i haven&#039;t gotten one. the only change i&#039;ve noticed is when i&#039;m supposed to have my period, i&#039;m very overly emotional. i didn&#039;t have that problem before the insert, but since that&#039;s the only side effect it was well worth getting it done!"
