Snowboard stance question?

ok i am 13 girl and i have been snow boarding for 6 seasons, about to be 7 and i was a regular for a stance. i skateboard goofy along with surf. when i was buying my burton feelgood today they asked if i was goofy or righty. i said i dont know anymore, they both feel awkward. so the guy pushed me wihtout knowing and i put my right foot first. saying i am goofy now. but when i think in my mind that i am going off a jump or box it seem good righty strange goofy. should i just wait till snow fall and see what feels right?
