"i had mirena for a year. insertion was a small pinch and not bad at all. i spotted the whole time i had it in, experienced more headaches, lower back aches and cramping. the spotting wasn&#039;t really a lot but i always had to wear a liner. my sex drive was low and i would get panic attacks and have horrible mood swings. i also gained like 15 lbs.  i had it taken out today so i am hoping i feel better. my husband is happy i am getting it out, he said i just wasn&#039;t the same with it."
