this thing is a monster that has taken over my body! i had mirena put in in January of 09 after having my second baby....thought it was a great and easy solution to the birth control issue...boy was i wrong. since i have had it i have been a mess...bleeding all the time, headaches, weight gain, loss of hair, shortness of breath, nervousness, constipation, inability to concentrate and BAD irritability. my poor husband is going to have a nervous breakdown. i am glad to hear that i'm not the only one though. i was a little worried that i was going CRAZY! i made an appointment today to have mine removed immediately!!! i'm going back to the good ole pills...forget this foreign object in my body! wouldn't recommend this to ANYONE!
