Which type of bc?

I'm going to the doctor soon to get on birth control since my boyfriend and I are about to live with each other. I'm not quite sure on witch one to get. I was looking at the IUD but we don't have that kind of money. My mom told me that if we go to a family planning clinic that I can get on the pill for free. I  tend to be a forgetful person, and I have really crappy work hours, I won't be able to always take it at the same time everyday. I need some type of idea or advice for the pill since we can't afford any other type of bc.
