"i had implanon inserted in july of &#039;09.  i didn&#039;t have a period at all until mother nature showed up...on new year&#039;s!  not the way i wanted to start 2010.  i have gained 10-15 pounds since getting implanon and have acne, mood swings, and i have bad moments where i don&#039;t even recognize myself. i don&#039;t like being moody. it&#039;s tearing my boyfriend and i apart."
