"i&#039;m 18 and i have had the implant for about 3 months. overall, it has been very effective for it&#039;s main purpose and my skin has improved massively. my periods are still regular but now last much longer (about 8 days) and are so light that using tampons is out of the question. i do experience more mood swings and often cry for no reason. the biggest side effect i&#039;ve noticed has been my weight, i have lost a lot of weight and have nearly no appetite and when i do eat i feel nauseous. i also can&#039;t drink alcohol without being sick all of the next day, not sure whether this is the implant but it only became an issue after getting it. i much prefer this method than the pill and would recommend, still waiting for my body to settle down!"
