Copper
"I got the copper IUD (the brand I have is the Mona Lisa) implanted about 4 hours ago and so far am pleased. I am 22, no kids. I took 800mg ibuprofen 30 minutes before and I took another 400mg an hour after. Insertion was painful even after they numbed my cervix a bit but truly not that bad. They warned me when it would hurt so I could anticipate it. It was all over very quickly and I had no trouble walking out of the clinic. About 15 minutes afterward I had some nasty cramps and pain set in, the ibuprofen did not really help but the heating pad has been somewhat helpful. I just sort of had to put up with it. I napped a bit and the cramps are now subsiding, so I hope they stay that way! No spotting or bleeding yet. Will update in 1 month."
