"i got this implant in sept 2012, and i&#039;m definitely looking forward to taking it out this coming sept.  the only pro here is that it is definitely effective. i&#039;ve been in a committed monogamous relationship for the duration of having this implant, we are a very &quot;active&quot; couple, and i&#039;m still kidd-o free w/o worry. the cons: i weighed in about 140 when i got this, and am currently weighing in at 167 - almost 30 lbs heavier in less then three years. disclaimer, i am now 31, so a small amount of this may also be due to slowed metabolism, but def not 30 lbs. i sometimes have a 2 month period, and i sometimes go two months w/o one, there is no predicting it. i have crazy mood swings for no reason, even when i&#039;m not on my period.    not worth it."
