"The scare tactics online are so ridiculous. I understand everyone's pain tolerance is  different but what boggles me is the women who have given birth saying that this 2 min (if that) procedure is worse. I mean, really? I almost changed my mind about the Paragard due to all the "worst pain of my life" stories. Ladies, get a grip. IT'S REALLY NOT THAT BAD! Two, quick intense period cramps that each last about 10 seconds. Some mild period - like cramping after. I have an insanely low pain tolerance and all I took was 2, 500mg  Naproxen. I was so scared after reading all the stories online and it was all for nothing. Trust me when I say if I can tolerate the procedure, anyone can. I'm a big baby. But obviously, not the biggest!"
