"i have been on the implanon a little over a year now. i have not had any periods besides a little spotting the first couple months. (yay for not having to pay for tampons &amp; chocolate!)  i love the fact of not having a period and not getting pregnant right now, but there are a few downsides to it. my downsides: i never had acne previously and i now have it really bad, i gained about 45 lbs, and i have horrible mood swings. it has its good and its bad to it, just be cautious of the side effects."
