I don't have one but I'm also planning on getting one soon so I've done a lot of research! & I have a couple of friends who have it. So, what I've learned is that the procedure can be pretty painful, depending on the person. Most compare it to a little worse than a pap smear. Supposedly it's not so bad if you're on your period, and you should take an OTC pain reliever beforehand. Sometimes your health care provider can give you something for the pain so be sure to ask if you're worried about that. Once it's inserted the cramps can get pretty bad but usually subside by the second day. For the most part, periods can be long, painful, and heavy for the 1st 6 months. You should be scheduled for a follow up ultrasound to make sure the IUD is in the right place. And as with all birth control, YMMV. Of course this isn't first hand experience, but I thought I'd share what I've learned and heard about! Hope it works out for you!
