"had the copper coil for 10 years with no probs just my periods slightly heavier. convinced by doctor to have mirena as it was so great ( even though i had no probs with the copper and no probs with heavy periods) i was sold. anyways all was fine for the first week then exactly 1 week later ( and nothing else in my life changed) i started to get manic, anxious and felt like i was running away from danger all the time. i wanted to cry as i felt so out of control and powerless. my blood pressure went up and i have a leaky heart valve and this is not good. so cross i was fooled. my hormones do affect my mood. some women like it i hate it with a passion!"
