Best method.

I had the copper IUD for about a year and a half but I got it removed because it decided to just float around in my uterus. I got on the pill but quickly stopped taking them because I would forget about them 3 days in a row. I have a Bf and we are very sexually active. We don't use anything, only the pull out method, BUT that's how I got my daughter lol i have no idea how to go about getting birth control because IDK what is best for me. So my questions: how did you ladies go about choosing the right birth control method and why did you choose the one you did?
