IUD too young?

So I'm 22 years young and I've been on birth control since I was 16. I've been on and off it for a little while. I've used the pills,the patch, and the shot. However I've come to the conclusion that I don't want to have any kids any time soon. So do you have to be a certain age in order to get an IUD inserted? I'm just wondering. Any comments about it would be helpful.
