Levonorgestrel
"Honestly, I am still one of the undecided... I have/had dysmenorrhia that lasted a full 7 days each month. My tubes were tied 20 plus years ago. Perhaps it is genetics that I am in the place I am today because my mother went through many of the same symptoms and eventually had a hysterectomy. After discovering a large submucosal fibroid that was removed, I started to experience sharp pain ( which escalated from simple cramps ) when my cycle hit. The Mirena is my last viable option before surgery. It was place a week and a half ago. Within 4 days of its placement and seeing my doctor again because of pelvic pain from the jabs and sticks I felt, I'd lost 2 pounds. More weight is coming off 3 days later but still have pain."
