ParaGard
"I got my Paragard about two months ago now. I love it! The only negatives I've encountered because of it is very intense cramps during the first four days of my period and occasional spotting while I'm not on my period, both of which I've never had to deal with before getting it inserted. As for the cramps- they're terrible (and I would describe myself as having a high pain tolerance), and can leave me short of breath if I don't keep up to date with Midol and Pamprin for the first 4-5 days of my cycle. If I do, it's completely manageable!"
