birth control
"My friend and I, both 18, got Mirena as birth control. She loves hers. The insertion was painful, but manageable- the side effects are what's really bad. Before, my period was short, light, and I have NEVER cramped. Since getting my IUD, I have consistantly bled heavily. Daily, I have crippling cramps to where I can no longer continue to drive or walk. I often wake up moaning in pain and crying. I got an ultrasound yesterday and everything looked fine. I'm not saying not to get Mirena, but I strongly recommend considering other options or being okay with dealing with the side effects. This has been a terrible experience for me, and a great experience for my friend so you can never really be sure how it will be for you."
