Unprotected Sex on Paragard IUD?

the IUD is a birth control, thats what it is for, i have had mine for almost 2 years and always have unprotected sex, the IUD is the best form of birth control besides abstaining, stop worrying its ok and so u know the pullout method is not full proof, my 3 year old is proof of that, but other forms of birth control and condoms and such are completely un needed
