What type of Birth Control??

Kristina
I'm going to be getting on or using birth control soon. But I just can't fathom having synthetic hormones put into my body. I've been on the pill before and it was fine but it was in high school and so long ago. 
So my question. What kind has the least amount of hormones and the most effective?
And what are your opinions on the pill?  and the copper IUD? I've heard the copper IUD is only a spermicide. But some have said bc I haven't had kids they don't recommend them bc it's more long term, etc. I like the idea of it. 
Thoughts????
