birth control?

Angelina
I'm considering birth Control, not only so I don't get pregnant, but to help my cramps cause I get them everyday if my period except for two days, and they're super bad, and recommendations on some? That are not the "pill"? 
I'm also really scared to try birth control cause of all the things I heard it can do to your body, am I just over thinking or do I need to be scared a wary of what I use?
