Wondering if anyone else have had problems with mirena iud. i have had it for a year now and only had my period once. about six months ago i started getting headaches that feel like my head is bruised or swollen, nausea, dizzyness, my left eye goes black when i pick stuff up not everytime but most, very tired all the time, random sharp pains in my lower stomach. i have been going to my doctor to see whats wrong but all my tests have come clear so far. im wondering if this tiny little iud that i tought was the best birthcontrol could be causing the problems
