birth control
"I'm 23 years old and have had my mirena for more than 2 years and I am in love with it. Insertion hurt for a few seconds but it was quick. I recommend taking a pain pill beforehand.  An hour after insertion, I went to class. I was a little tender for a couple of hours but I wasn't uncomfortable, I wasn't in pain and I couldn't feel the mirena. That month I had a light period for 2 weeks and I had some light spotting during the second month after insertion. I have been period-free since then. It's so liberating. All I have to do is have my doctor check its strings every year. Sex is comfortable and pain-free and I feel great. I haven't suffered from any negative side effects. I will probably get another one in 3 years."
