I been on the pill for 19 years. The pill has finally started to effect my blood pressure. The Doctor suggested using the Mirena because she has it and likes it. After reading things here I am a little scared now. Some the side effects of the Mirena are the same as the pill. Has anyone switch from the pill to mirena? What was the side effects? Is mirena side effect better or worst then the pill side effects? What is the changes you notice from the pill to mirena?
