Birth controls?

Destiny
I kinda want to get on some type of birth control, I'm nervous about getting pregnant. I have a two year old boy and a four month old boy. I don't need any more children right now, the two little stinker so have now wear me out in no time LOL 
SOO, my question is have any of you tried NuvaRing or The Patch? Those are really the only two I am interested in. I do not want a shot(hate needles) or anything injected or implanted in me! Lol
