"i absolutely loved the mirena and highly recommended it to anyone. but i have had some side effects which i am starting to believe they are from the mirena. i have had it in for 1 1/2 yrs and now i am thinking about having it removed. insertion was fine, no cramping, no acne. i did gain weight but can&#039;t say if its from the mirena. you can&#039;t tell it&#039;s in, its a great birth control. i actually got it in because my periods were very very heavy and were out of control. i have been experiencing anxiety the last 6 months and i have no idea why and seems to be getting worse, i have seen my ob and family doctor and they said i should have no side affect like this (anxiety).  i saw a new doctor, and she said it can. daughter thinks i&#039;ve been moody since i got."
