birth control
"I've had the Mirena for 3 months now, and I LOVE it. I'm 22, no kids and the pain was very tolerable during insertion. My periods have gone from ~5 days down to 1, and no cramps! I never even think about my period anymore. Downsides: I bled for for 3-4 weeks after I got it, and it made my acne flare up like crazy! I would still definitely recommend the Mirena for anyone though, the initial month-long adjustment was worth it!"
