"i have been on implanon since july 2009, and so far it has been the best form of birth control that i have came across.  i have not had a cycle since july, there have been no mood swings, weight gain, depression, hair loss, etc.  if anything i feel a lot more comfortable and happy now that i don&#039;t have to worry about that time of the month. the only thing i don&#039;t love is the small scar on my arm from the insertion.  other than that i would recommend it to other people who like me get migraines from the extra estrogen and are bad at taking pills every day."
