birth control
"I had Mirena put in about 6 months ago. I am 20 and have never had kids. The reason why I chose Mirena was basically because I could never remember to take the pill. I have had no weight gain or mood changes. When it was inserted it was pretty painful but it only took a few seconds. I spotted slightly for the first few weeks and had some pretty intense lower abdominal cramping if I wore tight pants that would only last for a few seconds. But after about a month, everything was back to normal. The benefits of Mirena totally outweigh the discomfort in the beginning."
