birth control
"I have had the Mirena IUD for a year now. I got it about 5 weeks after giving birth.  The procedure was simple and ALMOST pain-free.  I bled the 1st day it was inserted and haven't bled much since.  I do however have painful cramps that come and go, headaches, weight gain, lack of energy, and the Mirena is causing polycystic ovarian syndrome.  Somehow the Mirena string is gone, but the Mirena is still in place.  I like it because I don't have to do pills everyday or shots every 3 months, but the side effects for me have been the downside."
