Nosebleeds?

Meaghan • don`t look backwards or you`ll fall down the stairs.
I've been getting several nosebleeds these past few weeks, it was like every four to five days, now they're every other day or everyday. should I be concerned? I don't have allergies, and I'm healthy. I'm not sure what's wrong. the nosebleeds last for about 5 minutes each and just out of the right nostril.
