"first couple of months i had a longer then usual period. after about 2 months in it completely stopped although i had light craps and mood swings through out the first couple of months no weight gain. perks of having the implant, not having to worry about missed pills (although i was never good at taking pill form birth control) no shot and yet still having periods ! all around the implants been good to me. would highly recommend it to anyone with an irregular period!!!   haha good luck ladies!"
