"i love this birth control it&#039;s very effective. i get my period once or twice a year which is awesome. i don&#039;t have any side effects which is great. but i only have one complain i got a lump on my breast. thank goodness it&#039;s not cancer but it&#039;s painful.  i am currently taking antibiotics because that lump turn into an infection. i&#039;m about to remove the nexplanon and get another implant. just because i don&#039;t think that the lump is that serious."
