Fractured 5th metatarsal?

so i broke my 5th metatarsal about a week ago and i am seeing an orthopedist on monday. i have been pretty much off of it all week and keeping it in a fibergl cast. they gave me tylenol with hydrocodone for pain in the ER. the swelling has gone down completely and it doesnt really hurt that much anymore. i can limp along just fine as long as i keep it on the heel, i think i could probably put some more pressure on it than that but i dont want to make it worse. i have been taking calcium supplements too to help the cracked bone(it is only cracked, the bone isnt pulled apart). my question is am i going to be non weight bearing? i go to college and i have to walk to cles (all up hill and pretty far) and i really cannot get used to crutches as much as i have tried or been taught. any advice on what i should do?? thanks!
