"i&#039;m 25 years old with no children and i have mirena. i absolutely love it. the pill gave me acne, weight gain, mood swings and nausea. the nuvaring gave me blood clots. mirena has been a dream. insertion was no worse than a bad period cramp (again, i&#039;ve never had kids and it didn&#039;t hurt that bad) and i spotted for a few days. no biggie. i&#039;ve had oily skin and acne my whole life but am able to control it. mirena has made it no worse at all. i work out every day and have even been losing weight. so mirena has not made me gain weight. i just want to be a positive voice out there for mirena. before i got it i read message boards and it almost discouraged me from getting it. thankfully it didn&#039;t because it&#039;s been the best birth control ever."
