IUD's, The Bar, The shot etc

Hello! So I am currently taking birth control pills and have been for about 3 years now. I am usually pretty good about taking them but these past 6months or so I will forget at least one pill a month so my boyfriend and I will just use condoms for the rest of the month and it really sucks... I really want to get a 5 year IUD but I've just heard so many horror stories of girls who got the bar on their arm or the shot and have bled for six months (+) straight. Id love to hear some of your stories and experiences to help me decide! Thanks ladies!
