IUD experiences and opinions

I was recently taken off the Birth controll patch because I found out the estrogen was what was giving me intense and very frequent migraines. (Not just the patch all types of birth controll with estrogen in them)  Since then my doctor has told me my only option is to use condomes (not the end of the world, but I am allergic to latex so sometimes it's hard to find the brand I like) or get an IUD because they don't have estrogen I guess. (Can't remember the name of the one she suggested, it may be specific to that brand) my only concern is that I have never been pregnant and I know there are some risks involved with the IUDs. Just wondering what other peoples experiences with them have been like. Right now I'm to scared to risk it.
