Levonorgestrel
"Hi everyone! I had Skyla put in at the end of May this year & I am very happy with the results. The insertion process was painful, but seriously only for 3 seconds. Very quick & I was able to drive right after. I felt some cramping that day but it was nothing a little Tylenol couldn't fix. I would highly recommend this type of birth control to everyone, now that I have had it for a little while I can't believe that I was taking regular birth control pills for years before. I can just get up and go now! Don't let the bad reviews scare you, because Skyla is so worth it! You should expect some cramping while your body becomes accustomed to it, remember the uterus is a flat cavity so there's gonna be some getting used too. Give it a chance!"
