Levonorgestrel
"I got the Mirena implanted two days ago (Wednesday June 17, 2015) and so far it has been close to the easiest thing I've ever had to do. I'm 18 years old and I've never had a baby, I got the Mirena to use as a form of birth control. I took 880 mg of aleve 1 hour before my appointment and the whole process took maybe 10 minutes. I've only had one Pap smear before and she even had to dilate me a little bit but it didn't hurt worse than my worst period cramps- you just have to breathe through it. I had light spotting for the rest of the day and some mild cramps that felt better when I laid down and used a heating pad. Now I'm in no pain at all and I am happy and have energy and am VERY happy that I got this done!"
