HELP

Guys and gals... I need some serious help here, I rode last night and have encountered a bit of a problem. Everytime I jump, my board goes way behind me like kind of "raley-ish", but I am defintiely not meaning too. It is beginning to frustrate me, am I leaning to far back/ have my knees bent too much on my cut into the wake? I am clueless here all I know is that as soon as I get into the air my board goes behind me and the bottom side of the board faces to the sky, something seems screwed up in the way I am approaching the wake but I dont know what, any and all help more than appreciated.
