I just got it back in December. I had blood clot issues after I had my daughter and my doctor did not want me to use anything that involved hormones, and we had already decided we were not having any more children. So far it's been great, no fumbling with condoms or remembering to take a pill every day. And it can stay in for up to 10 years, but can also be removed if you want to get pregnant again. The only thing I've noticed is that my periods are a lot heavier (as in, must double up with a tampon AND a pad and change both frequently - more of a nuisance than anything) but they don't last long (3 to 4 days, usually, as opposed to a week). I'm not more crampy or anything though, compared to before. When it was inserted I was REALLY uncomfortable for the first 24 hours or so - like, worst period cramps ever. Taking Tylenol and soaking in a hot bath helped. After that it was fine.
