"I had Paragard inserted 7 months ago and I can honestly say it's gotten so much better over time! The first couple periods I would get sporadic very sharp pains that drugs wouldn't help. They were so wrenching that I was nervous I would keel over and people would get concerned. My periods initially were very crampy (sharp pains), heavy, and longer than normal. The last two periods I've had very minimal sharp pains (only at the start of it), and it lasted 2 days normal with a couple days spotting. That's better than more normal periods! Sometimes I get crampy after sex, but nothing too bad. My body reacted so much better lately and I'm very happy not to have a hormonal IUD and be paranoid of pregnancies!"
