"i had the copper iud for 3.5 months. my periods went from 2-3 days and super light (i never even need to wear tampons and sometimes barely liners) to 7-9 day periods that were heavy. i would feel contractions closer to my period (in addition to cramps). the pain with this iud was unbearable. anytime i stretched, moved, had sex, etc i could feel it. i had it checked at the hospital and was told it was in the right place. i got several infections (bladder infection/uti and 3 yeast infections) all within this timeframe. i had constant back pain. if i went to the bathroom, it would hurt to pee or when i pushed. once removed, i had instant relief and problems went away almost immediately. oh and a seizure after insertion."
