I've had two different IUDs. The first one worked GREAT! I can't remember which one it was because it was so long ago, in my early 20s. The second one was murder--terrible cramps and heavy heavy bleeding. It was a copper one--t-shaped, I think. I was only able to have it for a few months before I gave up on it.

I had my first child at 20, so I was a good candidate for an IUD. I thought it would be wonderful to have one again after I married my husband, but it wasn't. I think the newer ones are probably better than the ones I had. My experience indicates that if you don't like one version, you might want to try another.
