"i have used the paragard twice now. the first time i had it inserted was a month or so postpartum. the insertion was painful of course and i ended up hyperventilating due to the pain. the device was very effective though and i didn&#039;t get pregnant the whole time i was on it. i had regular periods, but of course they were heavier than normal and more painful than normal. as time went on the periods got more and more painful. i started having severe back pain. i&#039;d get these horrid back cramps that got worse and worse every period. eventually i couldn&#039;t take it anymore and had it removed. i just used condoms for a while afterwards. a few years later i decided to give it another shot. my experience was identical again and i had it removed again."
