Birth Control
"I am a 27 yr old mother of 1 and I have had the Mirena for a week. I chose not to read any reviews about it before I had it inserted. I had heard unpleasant stories, but after a talk with my Gyno, I decided this was right for me. 
The insertion of the Mirena was not pleasant. As with many other women, the moment it was inserted felt like a contraction with sharp abdominal pain and dizziness. This is called a vagal response and is normal. It only lasted for about 15 minutes and I was able to get up and get dressed and leave. I experienced bleeding that day and back pain and cramps for 3 days.  
Only complaint so far is occasional abdomen discomfort and my husband says he can feel it when we have sex."
