I have a Paragard. I have never been pregnant nor had a kyd. I never check mine. It has never given me any problems. In fact my doctor recommended it because I told him I wanted to get fixed, and we both agreed a Copper T might be my friend because I decided to avoid surgery - no sense in being cut open in a hospital, those places are germy!
Again, I have never had any issues with my Paragard. I don't ever bother to check on it. My boyfriend can't even tell it's there. I have had it since December 2009. I won't lie and say insertion didn't suck balls because it did. The cramps I had during my period for the first four months were hell without a heating pad and lots of Advil Liquigels. Is it worth it?? Hell yeah - my boyfriend and I can have spontaneous, passionate sex without anything interrupting anything, and the Paragard is hella effective and NO HORMONES which is what I wanted since I can't handle hormones, plus I don't have to do anything for the next nine years.
Any doctor who tells you they won't give you an IUD because you're nulliparous is an asshole - you should be able to find one who doesn't have his head planted in his ass who will do it. My gyn is the best in my region and his placements are so good that he has almost no expulsions amongst his patients - and he's up on all the latest developments. Ask your general practitioner for a reference for who is the best gyn in your region.
Anyone who can't find a doctor who will fix them due to being too young, get a copper T. It's as effective and can be left in well over 10 years. Those of us who got ours in our 30s can keep it until we're too old to squat out a brat, by then the doctor should be willing to accept the obvious.
Anyone living in the Puget Sound region, PM me and I'll give you the name and number of my doc.
