birth control

Hello everyone, I'm currently not on any form of birth control as I just can't find anything to suit, I have recently (a few months ago) had my copper coil removed and feel so much better for it my periods have also become regular. However I do now feel that I need something as I don't want to get pregnant, we are very careful but withdrawal isnt a long term solution. I know it's very individual but is there anything any of you would recommend? I'm leaning more toward a pill of some sort? Thanks
