birth control
"I have had 2 Mirena's.  I had my first one inserted immediately after my second child.  It was uncomfortable but not painful.  I had it for the full five year.  I loved it!  I had it removed and was pregnant with my third child within 3 months.  I had my second mirena inserted a year after birth.  This time it was much more painful at insertion.  Again, great experience for another 5 years.  I had no cramping, no menstrual cycle, and no "bad" side effects. Over the last 10 years I have gained 20 pounds. I never experienced any kind of Mirena crash.  For someone who does not want to worry about a daily or monthly birth control and wants something long term, I would recommend Mirena."
