Levonorgestrel
"I've had Mirena for exactly 6 days and I'm still experiencing minor cramping. The spotting only lasted for a day and a half. I've gotten used to the cramping but if it gets too annoying I just pop a Motrin. The process itself was extremely painful because I'd never experienced cramps before hand. I'd say the part that was painful though was the dilation of my cervix. The second day was much better. I didn't have a sex drive for the first 3 days but on the 4th day I was ready to go. My face is clearer than ever. No regrets. Results may vary guys. Make your GYN your bestie just to stay on top of things. Good luck!"
