There are two main types of IUDs, one that contains hormones (like those found in birth control pills) and one that does not. The big advantage to the IUD? You don't have to remember to take a daily pill (or use a weekly patch or a monthly ring), and in the long run, it may save you money.
Once the IUD is in place, it's basically birth control you can forget about (though you should check the string placement periodically). Therefore, most women end up discussing what it's like getting the IUD, or having it removed. How did your experience go?
