"i had the implanon inserted in october 2007 and loved it. absolutely no change in me at all. no periods no weight gain nothing. i then decided to have another in october 2010. nothing but trouble since. i&#039;m moody 99% of the time. have gained weight. absolutely no sex drive, i&#039;m 21. luckily no periods but constantly feel pregnant. took a test yesterday as i have had very tender nipples for days. test negative thank god! i&#039;m so emotional and will cry at the drop of a hat. been lucky in some respect as i still haven&#039;t had a period.
