"i had implanon inserted in may of 2009. i was a little scared at first because i was reading all the side effects and reviews. i absolutely love the implanon birth control. i had not weight gain, no mood swings, and no acne.  when i first got it i bleed regularly for about 6 months. it stopped, but since year 2 of me having it, i have had a regular period monthly that only last about 5 days. it is very, very effective...(believe me, it has been proven several times). i would recommend this to anyone that still wants kids, but wants them a little spread out in years."
