birth control
"Yes, ParaGard hurt like hell when it went in four years ago and the first few days left me achy. I occasionally have some cramping during my periods. But I will say, it was so worth it. No issues with pregnancy at all and none of the side effects from the high hormone pills I used to be on. These people who experienced crazy changes shouldn't be so harsh since the negative experiences are so rare. Also, I don't know if some of these side effects people are mentioning are directly related to the IUD...it is easy to blame something when it could be something else. Be informed and make the choice based on sound SCIENTIFIC research, not some  review."
