New to Brith Control!

Hey Ladies I am soon to be engaged, and wanted to get a head start on starting birth control. I am a little worried though because I have heard SOOO many women talk about all of the negative side effects of brith control and how it made them feel horrible, gain weight, or feel emotionally crazy. This being said I have thought of try Fertility Awareness Method or FAM. Has anyone on here tried that? Or what has peoples experiences been with Hormonal Brith Control? Does the craziness go away after the 3 month period? Any advice, tips, stories and experience is helpful for weighing my options!
