birth control
"I had my Mirena inserted 1/4/10 and I love it! I know everyone is different, but it has been great for me. I'm 24, never had kids, and was on the pill for the past 6 years. Insertion was uncomfortable and painful, but not horrid (and I have a low pain tolerance). However, my doc did give me a local (lidocain) which I'm sure made a huge difference and I would not do it without.  I felt dizzy and nauseous for the first hour after and relatively bad cramping for three hours. The next day I was a bit tender, and by day three I was my normal self. Had some very light cramping for two weeks and now nothing, not even my period. I did have a little acne at first, but that may have had to do with going off the pill. I've even lost weight."
