birth control
"I have had Mirena for almost a year now. I got it in October 2010. I am 17 years old with no children. Other birth controls did not work for me. So my OB/GYN and I decided to try Mirena as a last resort for my woman problems (cysts,heavy bleeding).  When I first got Mirena I was in terrible pain, but I had also never had children so my cervix was really tightly shut. The procedure lasted about 3 and 1/2 minutes then the pain lessened to intense period cramps.  After that I had my period for 2 months straight with serious mood swings, cravings and weight gain. I've gotten the weight off and am period free! LOVE IT!"
