"i got nexplanon in august of 2014. all around its effective.  my only issues are with occasional nausea, increased appetite and weight gain and horrible headaches. i am a little worried about the fact that i have zero libido and no desire to be intimate with my husband.  i can deal with the rest but that&#039;s a little nerve wracking. and it&#039;s really annoying because he reminds me of it every day. anyone else have this problem?"
