I'm 21 years old. I have used birth control pills before but decided to get the mirena IUD about 6-8 months ago. This is my first IUD. I have never been pregnant. I used to use condoms any time I had sex, but with the IUD I didn't think I had to. Also I didn't make him pull out, so he busted inside of me. Should I be worried? Do I need to use condoms even though it's in? Help!!!!
